Ecologists have discovered a food web beneath the waves of French Polynesia that is both unusual and spectacular. A small channel hosts up to 700 sharks - far more than it can support based on the number of fish living there. The predators survive by feasting every winter on huge numbers of grouper fish, which swim into the channel to spawn.
A new study by an international team of scientists reveals the exact timing of the onset of the modern monsoon pattern in the Maldives 12.9 million years ago, and its connection to past climate changes and coral reefs in the region. The analysis of sediment cores provides direct physical evidence of the environmental conditions that sparked the monsoon conditions that exist today around the low-lying island nation and the Indian subcontinent.
A new study suggests that the increasing acidification of the oceans is likely to interfere with the ability of fish to reproduce. Researchers found that elevated levels of CO2, which make the waters more acidic, saw significantly lower levels of spawning. However, other mating behaviours of the same species were unaffected by the souring of the oceans.

Nineteen graduate students in the School of Marine Sciences at the University of Maine are helping ensure that European fisheries sustainably utilize ocean resources.The students participated in 20 stock assessment student reviews for European fisheries in early June through the International Council for the Exploration of the Sea (ICES).
A warming ocean is taking its toll on California's popular and playful sea lions for a fourth straight year, with scientists now reporting lower birth rates depleting the population, and masses of young animals still washing up starving and stranded on beaches.
South Africa's great white shark population is heading for possible extinction after a rapid decline in numbers, say researchers. A six year study of the country's coastal waters concluded that only 350 to 500 great white sharks remain.
Tracking hawksbill turtles by satellite is yielding information crucial to the fight to save them from poachers, traffickers, and hunters.
Representative Sam Farr (CA-20) opened the Marine Technology Society and the House Oceans Caucus Congressional briefing this week by noting his attempts over 28 years in Congress “trying to develop as much interest in the ocean as there is in space.”
