Record number of whales in Antarctic Bay
Scientists have observed a “super-aggregation” of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula. The sightings, made in waters still largely ice-free deep into austral autumn, suggest the previously little-studied bays are important late-season foraging grounds for [...] -
Scientists Reveal New Technique to Monitor Coral Reef ‘Vital Signs’
With the world’s coral reefs threatened by coastal development, pollution, rising sea temperatures and other factors, scientists have developed a new method to monitor the health of these underwater ecosystems. -
Urchins Depend on Sea Temperature
The water temperature is of major importance for how well young sea urchins grow, new research reveals. In the wild the green sea urchin is found in water temperatures ranging from -1 to +20 °C, but scientists found the optimum temperature to be 10 oC -
How Life on the Surface affects Life on the Seafloor
Analysis of a comprehensive database has revealed strong links between biological productivity in the surface oceans and patterns of biomass and abundance at the seafloor, helping to explain large regional differences. The vast majority of the biological production in the world’s oceans occurs within sunlit surface waters – the “photic zone“. Through the process of [...] -
Why leatherback turtles linger in South Pacific
Tagging and tracking leatherback sea turtles has produced new insights into the turtles’ behavior in a part of the South Pacific Ocean long considered an oceanic desert. According to researchers at Stanford University, the new data will help researchers predict the turtles’ movements in the ever-changing environment of the open ocean, with the goal of [...] -
2011 is the Year of the Turtle
Turtle conservation groups are designating 2011 as the Year of the Turtle. The sex of some species of turtles is determined by the temperature of the nest: warm nests produce females, cooler nests, males. And although turtles have been on the planet for about 220 million years, scientists now report that almost half of the turtle [...] -
Robotic Fish could Monitor Corals
Researchers at Northwestern University have created a robotic fish that can move from swimming forward and backward to swimming vertically almost instantaneously by using a sophisticated, ribbon-like fin. The robot, created after observing and creating computer simulations of the black ghost knifefish, could pave the way for nimble robots that could perform underwater recovery operations [...] -
Thailand closes dive sites to save reefs
Thailand is closing 18 dive sites across seven marine national parks, including the Similan and Surin Islands. Over 80% of the coral at each site had been damaged by unusually warm sea temperatures. -
Winners announced in Ocean Art Underwater Photo Competition
The Ocean Art Underwater Photo competition, organized by the Underwater Photography Guide, has announced its winners for 2010. Judges included professional photographers Martin Edge, Chris Newbert, Marty Snyderman and Bonnie Pelnar. Over $67,000 worth of prizes were awarded to 77 photographers. There are 7 winners in each of 11 categories, including Wide-angle, Macro, Portrait, [...] -
Fish mucous cocoons: the mosquito nets of the sea
Researchers have found that fish have developed their own mosquito nets in order to get a good night's sleep.
