Generally, El Niño tends to turn into a La Niña event in the following June-July after its mature phase; however, the negative sea surface temperature anomaly (SSTAs) associated with La Niña events can persist for more than one year after peaking, resulting in a longer duration than that of El Niño. Scientists explain why El Niño decay faster than La Niña.
A new study, undertaken by a team of scientists from BIOS, the Bermuda Government Department of Environment and Natural Resources, and the University of Rhode Island, used DNA markers to characterize the genetic diversity of Bermuda's baitfish populations. The island's baitfish were shown to exist in highly mixed populations of up to six different species indicating that individual fish from multiple locations around the island contribute to a single gene pool.
Blue sharks use large, swirling ocean currents, known as eddies, to fast-track their way down to feed in the ocean twilight zone.
After years of federally mandated protection, scientists see signs that this once ecologically fertile area known as the Hawaiian-Emperor Seamount Chain is making a comeback.
Marine microbes with a special metabolism are ubiquitous and could play an important role in how Earth regulates climate.
Analyzing the full life cycle of long-term droughts and how they relate to El Niño and La Niña conditions in the Pacific Ocean could eventually lead to better prediction of damaging, multiyear droughts in the Southwestern US.
A team of researchers, led by international conservation charity ZSL (Zoological Society of London), has discovered that sharks are much rarer in habitats nearer large human populations and fish markets. The team also found that the average body size of sharks and other marine predators fell dramatically in these areas, where sharks are caught and killed intensively for their meat and fins.
Macroalgae is shown to be a major global contributor to carbon sequestration.
Today, the National Oceanic and Atmospheric Administration (NOAA) released the Status of US Fisheries Annual Report to Congress, which details the status of 479 federally-managed stocks or stock complexes in the US to identify which stocks are subject to overfishing, are overfished, or are rebuilt to sustainable levels.
An international collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT) , Japan, has found that hazardous chemicals were detected in plastics eaten by seabirds. This suggests that the seabird has been threatened by these chemicals once they eat plastics.
