Aboard the research ship RV Laurence M. Gould, cruising along Antarctica’s west coast, according to Carlos Moffat, chief scientist, Palmer Long Term Ecological Research Program: “Even as somebody who’s been looking at these changing systems for a few decades, I was taken aback by what I saw, by the degree of warming that I saw… We don’t know how long this is going to last. We don’t fully understand the consequences of this kind of event, but this looks like an extraordinary marine heatwave,”

Moffat: “It’s very difficult to warm the ocean, and so when we see these conditions, that really speaks to a very intense forcing.”

Notably absent from the debris was plastic from nations with lots of plastic pollution in their rivers. This was surprising, says Egger, because rivers are thought to be the source of most ocean plastic. Instead, most of the garbage-patch plastic seemed to have been dumped into the ocean directly by passing ships.This suggests that “plastic emitted from land tends to accumulate along coastal areas, while plastic lost at sea has a high chance of accumulating in ocean garbage patches”, Egger says. The combination of the new results and the finding that fishing nets make up a large proportion of the debris indicates that fishing — spearheaded by the five countries and territories identified in the study — is the main source of plastic in the North Pacific garbage patch.

Every 60 seconds the equivalent of a lorry-load of plastic enters the global ocean. Where does it end up? Right now, researchers simply don’t know. But in a bid to help find out, an ESA-led project developed floating transmitters whose passage can be tracked over time, helping in turn to guide a sophisticated software model of marine plastic litter accumulation.

Reconstructions from sedimentary records show that canyons undergo flushing infrequently (102- to 103-year time scales), and on passive margin canyons, this might occur only during periods of glacially lowered sea level and direct sediment supply (7, 12).

Although there are reports on CHH peptides in other crustacean taxa such as Armadillidium vulgare (Isopoda)22,23, Daphnia pulex (Cladocera)24 and Daphnia magna15, investigations beyond decapods have remained scant and the sequences of CHH/MIH/GIH genes in other crustacean taxa have remained elusive.

A computer simulation of refugees’ journeys as they flee major conflicts can correctly predict more than 75 percent of their destinations, and may become a vital tool for governments and NGOs to help better allocate humanitarian resources.

Mackenzie River

The Mackenzie River is a major river system in northwestern North America. It is exceeded only in basin size by the Mississippi-Missouri system. The entire Mackenzie River system is 2,635 miles long and passes through many lakes before emptying into the Beaufort Sea of the Arctic Ocean. The Mackenzie River alone is 1,025 miles long when measured from Great Slave Lake. It begins at Great Slave Lake where the elevation is 512 feet above sea level. Great Slave Lake can be as deep as 2,000 feet in certain places. It is filled with clear water on the eastern side and shallow, murky water on the western side. The headwaters of the Mackenzie River include numerous large rivers. The drainage basins of the Mackenzie River include the Liard River, Peace River, and Athabasca River. The ice that forms on the Mackenzie River over the winter months begins the break up in early to mid-May in the southern sections. Ice covering some portions of the Mackenzie River can break up as late as the end of May. The Mackenzie River basin is home to a very small and sparse population despite the natural resources available in this area. This area is home to muskrat, marten, beaver, lynx, and fox. Pulpwood and other small conifer trees can be found here. Petroleum and natural gas are usually the underlying reason larger settlements have formed in this area (Robinson 1999).
