Disturbance, colonization and development of Antarctic benthic communities

first_imgA decade has yielded much progress in understanding polar disturbance and community recovery—mainly through quantifying ice scour rates, other disturbance levels, larval abundance and diversity, colonization rates and response of benthos to predicted climate change. The continental shelf around Antarctica is clearly subject to massive disturbance, but remarkably across so many scales. In summer, millions of icebergs from sizes smaller than cars to larger than countries ground out and gouge the sea floor and crush the benthic communities there, while the highest wind speeds create the highest waves to pound the coast. In winter, the calm associated with the sea surface freezing creates the clearest marine water in the world. But in winter, an ice foot encases coastal life and anchor ice rips benthos from the sea floor. Over tens and hundreds of thousands of years, glaciations have done the same on continental scales—ice sheets have bulldozed the seabed and the zoobenthos to edge of shelves. We detail and rank modern disturbance levels (from most to least): ice; asteroid impacts; sediment instability; wind/wave action; pollution; UV irradiation; volcanism; trawling; non-indigenous species; freshwater inundation; and temperature stress. Benthic organisms have had to recolonize local scourings and continental shelves repeatedly, yet a decade of studies have demonstrated that they have (compared with lower latitudes) slow tempos of reproduction, colonization and growth. Despite massive disturbance levels and slow recolonization potential, the Antarctic shelf has a much richer fauna than would be expected for its area. Now, West Antarctica is among the fastest warming regions and its organisms face new rapid changes. In the next century, temperature stress and non-indigenous species will drastically rise to become dominant disturbances to the Antarctic life. Here, we describe the potential for benthic organisms to respond to disturbance, focusing particularly on what we know now that we did not a decade ago.last_img read more

HMS Somerset to Return Home After Six-Month Deployment

first_img February 22, 2012 View post tag: Navy Back to overview,Home naval-today HMS Somerset to Return Home After Six-Month Deployment An emotional homecoming is expected when the Royal Navy frigate HMS Somerset returns to HM Naval Base Devonport, Plymouth, on Friday (24 February) following a six-month deployment to the Middle East.HMS Somerset’s second-in-command Executive Officer, Lieutenant Commander Ben Aldous, said:“Our homecoming is a long and eagerly anticipated conclusion to a lengthy deployment. “Although Somerset is well-equipped and her ship’s company well-trained, it cannot be under-estimated how well the spirit and moral of the team is bolstered by the support of family and friends at home. It is going to be an emotional day.”HMS Somerset has remained at sea for up to six weeks continuously at any one time and visited Oman, United Arab Emirates, Jordan, Saudi Arabia, Tanzania and the Seychelles.Whilst in various ports the crew engaged with their host nations on a variety of issues ranging from maritime security tactics to playing football; all of which served to strengthen international co-operation based on the shared need to protect maritime trade routes.The crew of the Type 23 frigate achieved some operational successes as well as providing life-saving assistance to stranded fishermen.The homecoming is expected to be very moving; many of the sailors have not seen loved ones for many months, including separation over Christmas. As well as crowds waving to welcome the ship at Devil’s Point in Plymouth Sound, families will gather inside the naval base and joined by the rousing music of the Band of Her Majesty’s Royal Marines.Throughout her deployment Somerset’s ship’s company have remained ready to respond to any tasking. She has predominantly been working under Combined Maritime Forces (CMF) as part of a task force which patrols the Red Sea, Gulf of Aden, Indian Ocean and the Gulf of Oman.It is a multi-national endeavour and exists to create a lawful and stable maritime environment free from terrorism, smuggling and piracy. Her principal mission was to deter, disrupt and defeat such actions.Powerful and versatile with the capability to operate anywhere in the world, the Type 23 frigate is the mainstay of the Royal Navy’s surface fleet. The 13 Type-23 frigates form half of the frigate/destroyer force in the Royal Navy. Originally designed for the principal task of anti-submarine warfare, they have evolved into multi-purpose ships.As well as warfare roles, these ships conduct embargo operations using boarding teams, disaster relief work and surveillance operations.[mappress]Naval Today Staff , February 22, 2012; Image: royalnavy HMS Somerset to Return Home After Six-Month Deployment View post tag: after View post tag: Return View post tag: HMS View post tag: Navalcenter_img View post tag: home View post tag: Somerset View post tag: News by topic Training & Education View post tag: Six-month View post tag: Deployment Share this articlelast_img read more

UK: HMS Lancaster Helps Detecting Three Cannabis Plantations

first_imgThe Ship’s Company of HMS Lancaster have been praised by police for helping detect three cannabis plantations in the Caribbean resulting in the seizure of 204 plants.HMS Lancaster is currently deployed on patrol in the North Atlantic and Caribbean and was on a visit to the island of Anguilla when the drugs bust took place.At the request of the Royal Anguilla Police Force (RAPF), Lancaster’s Lynx helicopter took to the air with two island detectives onboard to scour the island for cannabis plantations. During their sortie three potential sites were identified, photographed and recorded.As soon as the helicopter touched down, a team of policemen from the RAPF raided the locations and, despite making no arrests, seized 204 cannabis plants. A spokesman for the RAPF said:“Members of the Royal Anguilla Police Force and a crew from HMS Lancaster carried out a Cannabis radication Operation in various parts of Anguilla namely North Hill, Cedar Village and Sandy Hill.“During this operation a total of 204 cannabis plants were seized.“This operation comprised of resources from HMS Lancaster’s aviation crew and officers of the RAPF who were airborne and officers who made up several ground teams. I would like to thank the crew of HMS Lancaster for their assistance and look forward to working with them again.”HMS Lancaster’s Lynx helicopter is piloted by Lt Chris Easterbrook. He said:“The island is covered in dense foliage but between the aircrew and the RAPF officers, we were able to spot three sites which we suspected of being cannabis plantations. Two sites were fairly modest in size but one was the largest I have seen since we have been in the Caribbean.“It was an absolute pleasure to work with the RAPF and incredibly satisfying to know that our cooperation furthered Anguilla’s efforts to eradicate cannabis.”HMS Lancaster is visiting British Overseas Territories as part of her regional defence engagement activities while on a six-month deployment in the Caribbean and North Atlantic. She will also provide reassurance and security to the islands at the start of the Caribbean hurricane season.This week the Type 23 frigate visits Puerto Rico to pick up a law enforcement detachment from the US Coast Guard in order to fully begin counter narcotic operations.HMS Lancaster’s Commanding Officer, Cdr Steve Moorhouse, said:“The Royal Navy’s primary role in the Caribbean is the security of the overseas territories, be that throughour presence in the region, our support following a natural disaster or in assisting regional law enforcement agencies.“This particular operation in concert with the Royal Anguilla Police Force is just one example amongst many of the Royal Navy supporting the territories in their policing efforts.“Counter drugs operations form a significant part of the Caribbean policing effort and I am delighted that Lancaster has been able to support Anguilla and demonstrate our commitment to protecting the interests of our overseas territories.”The Royal Anguilla Police Force has now destroyed the cannabis plants.[mappress]Press Release, July 18, 2013; Image: Royal Navy View post tag: Cannabis View post tag: HMS View post tag: Naval July 18, 2013 UK: HMS Lancaster Helps Detecting Three Cannabis Plantations View post tag: three View post tag: Defence View post tag: Navy View post tag: Detecting View post tag: helps View post tag: Defense Back to overview,Home naval-today UK: HMS Lancaster Helps Detecting Three Cannabis Plantations View post tag: News by topic View post tag: Plantations View post tag: Lancaster Share this articlelast_img read more

HHS awards $102 million for new flu drug

first_imgJan 5, 2007 (CIDRAP News) – In an effort to expand the pool of antiviral drugs for influenza, the US government yesterday awarded a $102.6 million contract to BioCryst Pharmaceuticals Inc. of Birmingham, Ala., to develop peramivir, a new neuraminidase inhibitor.The Department of Health and Human Services (HHS), in a press release, said peramivir has been effective against several influenza strains in laboratory studies. HHS said the contract will cover production of the investigational drug, phase 2 and 3 clinical studies, and validation of manufacturing processes.Research under the contract will include tests involving the deadly H5N1 avian flu virus and may include research on the possible preventive use of the drug, according to HHS. BioCryst officials said the drug has been shown to help animals survive H5N1 infection.”Antivirals are an important element of our pandemic influenza preparedness efforts,” said HHS secretary Mike Leavitt in the press release. “Our antiviral strategy includes not only stockpiling existing antiviral drugs but also seeking out new antiviral medications to further broaden our capabilities to treat and prevent all forms of influenza.”Licensed drugs in the neuraminidase inhibitor class are taken orally (oseltamivir) or by an inhaler (zanamivir). However, peramivir is under development as a parenterally administered drug, meaning it can be given through intramuscular and intravenous routes.HHS said a parenteral neuraminidase inhibitor may be particularly useful in hospital emergency departments for treatment of patients who have life-threatening flu. Parenteral injection could permit rapid buildup of peramivir to high levels throughout the body and allow treatment of people too ill to take medications by mouth, the agency said.In a news release, BioCryst said its laboratory tests have shown that peramivir, an inhibitor of influenza A and B neuraminidases, is more potent than currently available drugs in its class and is active against antiviral-resistant flu strains. The company said high doses of injectable formulations have been safely administered to healthy people, and the drug has been found to promote survival in animals infected with the H5N1 virus.At a BioCryst teleconference that followed the HHS announcement, Charles Bugg, PhD, the company’s chairman and chief executive officer, said the contract allows the company to move peramivir as quickly as possible through clinical development.HHS said awarding the contract to BioCryst is part of a larger initiative to support the development of new treatments and vaccines that would allow the United States to respond quickly to a flu pandemic.Bugg said both the intramuscular and intravenous formulations of peramivir will go through phase 2 and 3 clinical trials. The intramuscular formulation will be tested against a placebo in outpatients, and the intravenous trial will likely test peramivir against oseltamivir in hospitals.Enrollment of patients for the phase 2 trials will begin this flu season in the United States, Canada, and Europe, Bugg said, adding that the company has identified sites in the southern hemisphere that could be used to fill this year’s phase 2 study groups or facilitate an early start on phase 3 studies. He said BioCryst is also identifying sites in Southeast Asia, where flu outbreaks occur year-round, that might be added to the study.Bugg said the HHS contract to develop peramivir is subject to an emergency use authorization that would allow the department to stockpile the drug before approval by the Food and Drug Administration (FDA) if clinical data show it to be beneficial.Jonathan Nugent, vice president of corporate communications at BioCryst, told CIDRAP News that the company hasn’t ruled out developing oral or inhalational formulations of peramivir in the future. He said the company couldn’t speculate on how long it might take for the drug to win FDA approval. HHS said the FDA has given peramivir “fast track” status, which would expedite the agency’s review of BioCryst’s application.See also:Jan 4 HHS press releasehttp://www.hhs.gov/news/press/2007pres/01/20070104a.htmlJan 4 BioCryst press releasehttp://investor.shareholder.com/biocryst/releasedetail.cfm?ReleaseID=224367last_img read more

Poll shows many unready for public health crisis

first_imgMay 8, 2007 (CIDRAP News) – A recent survey sponsored by the American Public Health Association (APHA) indicates that about a third of Americans have made no preparations for a public health emergency and nearly 90% have prepared less than they think they should.The APHA survey, released in April at an expert roundtable discussion during National Public Health Week, was recently posted on the association’s Web site. The online survey was conducted in February by Peter D. Hart Research Associates, based in Washington, DC. It included 925 adults and sought the input of several specific groups, including mothers with children younger than 5, hourly wage workers, and adults who have chronic medical conditions.The survey group also polled 120 employers and 150 school superintendents and interviewed a small group of regional food bank administrators and local food panty and soup kitchen managers.Among the survey’s key findings:Thirty-two percent of the public have taken no special steps to prepare for a public health emergency that could leave them short of food, water, or medication.An 87% majority said they knew they had not done enough and could do more to prepare for a public health emergency.Forty percent of respondents said they had taken steps to prepare in the past, such as after the Sep 11 terrorist attacks, but had since let their plans lapse.More than a quarter (27%) said they were prepared for an emergency, but only about half (14%) had the 3-day supply of food, water, and medication currently recommended by the American Red Cross for general disaster planning.Close to half—46%—of respondents had not assembled a disaster supply kit.Georges C. Benjamin, MD, executive director of the APHA, said in a press release that the survey findings show public health officials have a long way to go to prepare the nation for public health emergencies.”No one can predict where the next natural disaster, major storm, or disease outbreak will strike, but when it does, it is likely to disrupt basic services, leaving people without electricity, water, food or needed medications,” he added.In the press release, the APHA said the survey shows that several vulnerable subgroups are lagging in their emergency preparedness efforts. For example, 58% of mothers with young children said they did not have a 3-day supply of water for their families, and only 61% of people with chronic health conditions had at least a 2-week supply of medication.The 17-page survey report says the term “public health crisis” does not resonate with people, though respondents reported being are concerned about specific events, such as natural disasters, that might lead to one. Only 26% thought that a public health crisis would affect their family in the next year or two, but 57% thought a severe storm might strike their area in the next few years, 47% thought an infectious disease outbreak such as the flu is likely, and 43% believed a foodborne disease outbreak is likely.In other findings, researchers reported that only 37% of employers believed that a public health crisis would affect their business during the next few years, and only 18% said they could continue paying their employees if business operations were interrupted. Though 63% of employees realized they might not be paid during a public health crisis, only 15% had saved enough money to provide for their families if such an event occurs.School administrators generally reported a high level of preparedness in the form of evacuation, communication, and community sheltering plans, but few said they had enough drinking water or food to last students for 3 days.Representatives of regional food distribution centers said they had devoted a lot of time and resources to preparedness planning, but those from local pantries or food shelves reported they were not prepared for public health emergencies, according to the APHA.All groups that were surveyed said cost was a major barrier to their preparedness actions.Greg Dworkin, MD, one of the editors of the FluWiki, an interactive pandemic planning Web site, told CIDRAP News he commends the APHA for commissioning the survey and said it’s important to gauge the public’s preparedness opinions from time to time, rather than making assumptions.The survey results suggest that preparedness messages are getting through to the public, but that people are not following through with action, said Dworkin, who is chief of pediatric pulmonology at Danbury Hospital in Danbury, Conn. “That’s a real problem: the public hears the information, but the next question is how they process it,” he said.Some public health officials are overly concerned that the public will overreact or panic if they use specific terms when referring to public health threats, but not using specific terms represents a missed opportunity, Dworkin asserted. “The message has to be crystal clear. Say ‘pandemic’ if that’s what you mean,” he said.Also, it likely takes sustained, high-profile, and consistent messages to successfully persuade the public to prepare for public health emergencies, Dworkin said. “It’s a marathon, rather than a sprint,” he added.See also:APHA press releaselast_img read more
