Mediterranean Warming

A new report, whose main conclusions are being presented on Thursday in Barcelona by the Mediterranean Institute of Biodiversity and Ecology, shows that the temperature increase in the Mediterranean region has already reached 1.5ºC above pre-industrial levels, which means that the warming effect in this area is 20% faster than the global average.

Temperature and salinity double in Mediterranean

The Mediterranean is responding very quickly to global warming and the rate of evaporation is higher than precipitation and fluvial supply. Temperatures and salinity is also increasing at two and a half times the rate at the midway point in the twentieth century and higher than that of the oceans, according to research published in Scientific Reports.

The data of the study shows that since the end of 1993 until today, the temperature and salinity of the water coming from the eastern Mediterranean, between 300 and 600 meters below sea level, have experienced significant variations. In particular, the rapidity with which they are increasing is two and a half times that seen in the eastern Mediterranean in the second half of the twentieth century and is much higher than that seen in oceans.

Rising Temperature and Acidity Threaten Mediterranean

The temperature and acidity in the Mediterranean Sea are rising, and researchers are worried it will lead to extinction of native species.

Villefranche-sur-Mer oceanographic laboratory in the south of France released a study that said the ocean’s acidity has been rising on average of 7 percent a year between 2007 and 2015 and the water temperature rose 0.7 percent over the same period.

These rates are higher than any ocean in the world, researchers said.

National Scientific Research Centre (CNRS) director of research, Jean-Pierre Gattuso said the change in temperatures and acidity has already changed the ecology of the ocean.

“There are species that come from the southern coasts of the Mediterranean, so we end up seeing a Mediterranean that is becoming almost subtropical,” he said.

And he’s worried that native species are going to die out, like the posidonia, a seagrass native to the Mediterranean that provides oxygen to fish.

Other species that could face extinction in the ocean are oysters, small molluscs, coral, and mussels.

New Whale Stranding Is Painful Evidence for Naval Sonar Risks

On April 1, while the U.S. and other navies played war games somewhere offshore, Cuvier’s beaked whales began stranding along the southern coast of Crete. Those on the scene knew right away what they were dealing with, for the strandings were only the most recent in a line of similar calamities in the region, going back two decades. And in this case, as in the previous ones, all signs pointed to the U.S. Navy and its allies.

Cuvier’s beaked whales are a remarkable species. They have the deepest recorded dives of all marine mammals, some descending an astonishing 9,500 feet (3,000 meters) below the water’s surface before coming up for air. Favoring deep water, they don’t strand nearly as often as coastal species, and they don’t strand in large numbers, and they don’t strand New Whale Stranding Is Painful Evidence for Naval Sonar Risksalive.

Yet, that is exactly what happened on April 1. Beginning around noon, three Cuvier’s beaked whales came ashore in one spot along the Cretan coast, two others beached some 10.5 miles (17 kilometers) further west, and two more turned up another mile or two from there. All were alive when they stranded; rescuers managed to return most to the water, but, based on past experience, biologists in the region fear that they stranded again or perished at sea.

For the last week, the U.S., Greek and Israeli navies have been running a joint military exercise off Crete known as Operation Noble Dina. The exercise includes anti-submarine warfare training, which requires the use of high-powered military sonar.

Each of these events is tragic in its way, but this one feels particularly cruel. Just last year, the Scientific Committee of the Agreement for the Conservation of Cetaceans in the Black and Mediterranean Seas (ACCOBAMS), drew a map where sonar training should be avoided. One area on the map is off southeastern Crete — exactly where the new mass stranding occurred — around a highly sensitive marine area known as the Hellenic trench. But Greece fought the recommendation, and it wasn’t adopted.

Now experts are despairing that, with stranding after stranding, the region’s beaked whale populations are being decimated.

Beaked whales that have died from sonar exposure — at least the ones recovered in time for investigation — have suffered from a suite of severe, telltale pathologies, similar to those seen in decompression sickness, or the bends. Sonar is believed to kill them by disrupting their dive patterns. The ones that reach shore are considered the tip of an iceberg.
