An uninhabited Pacific island has come top of the first comprehensive ocean health index, which compares all the world's coastal countries and scores them for how well the seas around them benefit both man and nature.

Tiny 4.5 sq km Jarvis island, halfway between Hawaii and the Cook Islands, was briefly mined for seabird fertiliser in the 19th century but both the waters around it and the island itself have been left more or less untouched since then, which accounts for its top score of 86 out of 100 compared with a global average of 60.

Researchers find that commercial ships travel across most of the globe and could provide better warnings for potentially deadly tsunamis; this finding came as a surprise because tsunamis have such small amplitudes in the deep water, in contrast to their size when they reach the coastline, that it seemed unlikely that the tsunami would be detected using GPS unless the ship was very close to the source and the tsunami was very big

Commercial ships travel across most of the globe and could provide better warnings for potentially deadly tsunamis, according to a study published by scientists at the University of Hawaii – Manoa (UHM) and the National Oceanic and Atmospheric Administration’s Pacific Tsunami Warning Center.

New studies show impact of BP's Deepwater Horizon disaster on dolphins and other marine wildlife may be far worse than feared.

A new study of dolphins living close to the site of North America's worst ever oil spill – the BP Deepwater Horizon catastrophe two years ago – has established serious health problems afflicting the marine mammals.

The report, commissioned by the National Oceanic and Atmospheric Administration [NOAA], found that many of the 32 dolphins studied were underweight, anaemic and suffering from lung and liver disease, while nearly half had low levels of a hormone that helps the mammals deal with stress as well as regulating their metabolism and immune systems.
