| RISING SEA TEMPERATURES BRING COMMON DOLPHINS TO NORTHEAST SCOTLAND
Oxford, 12 July 2007. Scientists from the Cetacean Research and Rescue Unit (CRRU) in Banff, Scotland, and volunteers from Earthwatch, the environmental charity, were dazzled this week when they were joined by over 300 common dolphins in the Outer Moray Firth. This is the first time the team have ever recorded common dolphins (Delphinus delphis), a warm water dolphin species, in these coastal waters in 10 years of studying cetaceans in the North Sea. | Het Rijksinstituut voor Kust en Zee (RIKZ) richt zich op alle zoute en brakke wateren van Nederland, plus de kust. Als een van de zes specialistische diensten van Rijkswaterstaat verzamelt en levert het RIKZ kennis van al wat de zee aangaat, ter bevordering van:
duurzaam gebruik van estuaria, kusten en zeeën en bescherming tegen overstroming. | Humboldt squid on the move
Over the last five years, large, predatory Humboldt squid have moved north from equatorial waters and invaded the sea off Central California, where they may be decimating populations of Pacific hake, an important commercial fish. Ironically, these squid may have benefited from the decline of large tuna and billfish in the Equatorial Pacific, which previously preyed upon and competed with the Humboldt squid for food. This biological shift is documented in an article by postdoctoral scholar Louis Zeidberg of Stanford University and senior scientist Bruce Robison of the Monterey Bay Aquarium Research Institute in the July 31, 2007 edition of the Proceedings of the National Academy of Sciences. | NOAA's National Marine Fisheries Service is the federal agency, a division of the Department of Commerce, responsible for the stewardship of the nation's living marine resources and their habitat. NOAA's National Marine Fisheries Service is responsible for the management, conservation and protection of living marine resources within the United States' Exclusive Economic Zone (water three to 200 mile offshore). Using the tools provided by the Magnuson-Stevens Act, NOAA's National Marine Fisheries Service assesses and predicts the status of fish stocks, ensures compliance with fisheries regulations and works to reduce wasteful fishing practices. Under the Marine Mammal Protection Act and the Endangered Species Act, NOAA's National Marine Fisheries Service recovers protected marine species (i.e. whales, turtles) without unnecessarily impeding economic and recreational opportunities. | The International Coral Reef Action Network (ICRAN), established in 2000, is a global partnership of coral reef experts who are working to halt and reverse the decline of the health of the world's coral reefs. Made up of some of the world's leading coral reef scientists and conservation groups, ICRAN partners have created a globally integrated action plan to manage and protect coral reefs, based on recommendations from the International Coral Reef Initiative (ICRI). The International Coral Reef Action Network is a coordinated response to ICRI's urgent call to protect coral reefs. | Melting glaciers will dominate sea-level rise - NewScientist.com news service
Ice melt from small glaciers and ice caps will be the dominant cause of sea-level rise this century, according to new research. Scientists have previously suggested that the ice sheets of Antarctica and Greenland would be most responsible for rises as the Earth warms, as they hold the overwhelming majority of the world's frozen water.
Now an international team led by Mark Meier at the University of Colorado in Boulder, US, has found that glacial melt and the "calving" of icebergs into the ocean will account for 60% of all sea-level rise attributed to melting ice (Science, DOI: 10.1126/science.1143906. That is equivalent to an estimated 10 to 25 centimetre rise by 2100. | | | | | | | | | | | | | | | | | | | | | |
