Using satellite and other data, scientists have discovered that sea surface temperatures and sea level pressure in the North Pacific have undergone unusual changes over the last five years. These changes to the North Pacific Ocean climate system are different from those that dominated for the past 50-80 years, which has led scientists to conclude that there is more than one key to the climate of that region than previously thought.

According to a study by Nicholas Bond, J.E. Overland and P.

More than 250,000 loggerhead and 60,000 leatherback turtles are estimated to be inadvertently snared each year by commercial longline fishing, with up to tens of thousands dying, according to the first global assessment of the problem. The researchers who conducted the assessment said that, although their numbers are estimates, they are firm enough to warrant the development of rules for fishing equipment and practices to reduce or avoid such losses.

Early life may have lived very differently than life today

As two rovers scour Mars for signs of water and the precursors of life, geochemists have uncovered evidence that Earth’s ancient oceans were much different from today’s. The research, published in this week’s issue of the journal Science, cites new data that shows that Earth’s life-giving oceans contained less oxygen than today’s and could have been nearly devoid of oxygen for a billion years longer than previously thought. T

Certain ions bouncing around on the ocean’s surface and in droplets formed by waves may play a role in increasing ozone levels in the air we breathe, new research suggests.

These ions cover the surface of the sea in an ultra-thin blanket – about one-millionth the thickness of a sheet of paper. Researchers call this region the “interface.”

Using a technique that employs highly accurate laser beams, chemists for the first time saw the actual structures formed by these halo

Fossilised remains of sea creatures are commonly found in rocks in the mountains of the Basque Country. So, at some time in the past, Euskal Herria was under the sea. For example, during the Palaeocene period, some 65-55 million years ago. The region was then subtropical, and similar in appearance to the Australian Coral Reef.

Along the Bizkaia and Gipuzkoa coast, around Eibar, in Irati and in Urbasa, for example, we can see Palaeocene outcrops at the surface. During that period there were

Salmon farms in British Columbia may pose a threat to wild salmon stocks, a paper published today in the Canadian Journal of Fisheries and Aquatic Sciences claims. The paper presents evidence that native fish sampled near the farms are more heavily infected with parasitic sea lice. Lead author Alexandra Morton, a registered professional biologist and private researcher, believes the parasites multiply on the farms and are then transmitted to juvenile native salmon, causing recent drastic declines in
