Latest Census of Marine Life Stories
In an unprecedented effort that will be published online on the 28th of July by the international journal Nature, a team of scientists mapped and analyzed global biodiversity patterns for over 11,000 marine species ranging from tiny zooplankton to sharks and whales.
Scientists have just returned from a voyage with samples of rare animals and more than 10 possible new species in a trip which they say has revolutionized their thinking about deep-sea life in the Atlantic Ocean.
Microbes and zooplankton may be difficult to see, but they are playing an important role in the Census of Marine Life as explorers and researchers are attempting to catalogue the smallest, hardest-to-find marine species in four of the 14 Census field projects.
A British scientific expedition has discovered the world's deepest undersea volcanic vents, known as 'black smokers', 5000 meters deep in the Cayman Trough in the Caribbean.
Some regions of the deep ocean floor support abundant populations of organisms, despite being overlain by water that contains very little oxygen, but global warming is likely to exacerbate oxygen depletion and thereby reduce biodiversity in these regions, they warn.
Leaders of the Census of Marine Life said on Thursday at the annual meeting of the American Association for the Advancement of Science that in a decade-long search for new ocean life, thousands of new species have been discovered across the globe.
Marine Biologist Huw Griffiths from British Antarctic Survey (BAS) is involved in a major international investigation into the distribution and abundance of Antarctica's vast marine biodiversity â€“ the Census of Antarctic Marine Life (CAML).
Census of Marine Life scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight - creatures that somehow manage a living in a frigid black world down to 5,000 meters (~3 miles) below the ocean waves.
NOAA and Norwegian researchers recently completed a comparative analysis of marine ecosystems in the North Atlantic and North Pacific to see what factors support fisheries production, leading to new insights that could improve fishery management plans and the ecosystems.
Census of Marine Life historians meeting in Vancouver, Canada, say they have reconstructed images of past sea life that boggle the imagination. The researchers said they used such sources as old ship logs, literary texts and tax records to reconstruct what life in the ocean was like prior to the early 1800s. Before oil hunters harpooned whales by the hundreds, the ocean around New Zealand teemed with about 27,000 southern right whales - roughly 30 times as many as today, the scientists said....
