Sediment cores collected from the seafloor off Southern California reveal that plankton populations in the Northeastern Pacific changed significantly in response to a general warming trend that started in the early 1900s. As ocean temperatures increased, subtropical and tropical species of small marine organisms called foraminifera (forams) became more abundant. Forams that live in cooler waters decreased, especially after the mid-1970s. These changes are unlike anything seen during the previous 1,4
Scientists at the University of Liverpool are working with leading oil companies to further understanding of the nature of oil and gas reservoirs within deeply buried submarine channels.
Professor Stephen Flint and Dr David Hodgson, from the Department of Earth and Ocean Sciences, have been awarded £1 million by a global consortium of 11 of the world’s leading oil companies to study how sand is transported through and deposited in deep-sea submarine channels. Scientists will study a
The diversity of marine life in the Gulf of Maine region is much greater than previously thought
The Gulf of Maine Program of the Census of Marine Life, with the Huntsman Marine Science Center of St. Andrews, New Brunswick, announced today the first count of known marine species in the Gulf of Maine region — more than 50% larger than previous estimates. The count is 3,317 species and includes both year-round species and those that migrate to the region seasonally. The Canadian-US p
The United Nations General Assembly, meeting in New York, has proclaimed the year 2008 to be the United Nations International Year of Planet Earth (Note 1). The Year’s activities will span the three years 2007-2009.
The Year’s purpose, encapsulated in it strapline “Earth sciences for society”, is to: Reduce risks for society caused by natural and human-induced hazards Reduce health problems by improving understanding of the medical aspects of Earth science Discove
Scientists use deep ocean historical records to find an abrupt ocean circulation reversal caused by greenhouse gas warming
New research produced by scientists at Scripps Institution of Oceanography at the University of California, San Diego, helps illustrate how global warming caused by greenhouse gases can quickly disrupt ocean processes and lead to drastic climatological, biological and other important changes around the world. Although the events described in the research unfol
Researchers have developed a new tool to help them study endangered whales – autonomous hydrophones that can be deployed in the ocean to record the unique clicks, pulses and calls of different whale species.
Those efforts are leading to some surprising findings, including the discovery by a team of researchers of rare right whales swimming in the Gulf of Alaska.
“There has been only one confirmed sighting of a right whale in the Gulf of Alaska since 1980, so discovering
