New species and surprising findings in the Mariana Trench

The Mariana Trench located in the Western Pacific near Guam hosts the deepest place on earth, and has been the focus of high profile voyages to conquer its deepest point, Challenger Deep. A recent expedition to the Trench onboard Research Vessel Falkor targeted multiple depths and found active thriving communities of animals. The expedition set many new records such as the deepest rock samples ever collected and new species including the deepest fish ever recorded.

Warmest oceans ever recorded -- ScienceDaily

This summer has seen the highest global mean sea surface temperatures ever recorded. Temperatures even exceed those of the record-breaking 1998 El Nino year.

Figure 1: a) NOAA Sea Surface Temperature anomaly (with respect to period 1854-2013) averaged over global oceans (red) and over North Pacific (0-60oN, 110oE-100oW) (cyan). September 2014 temperatures broke the record for both global and North Pacific Sea Surface Temperatures. b) Sea Surface Temperature anomaly of September 2014 from NOAA's ERSST dataset.

Satellites expose mysteries of the deep ocean | Science News

A new comprehensive map of Earth’s seafloor reveals never-before-seen features hidden deep below the waves, including thousands of uncharted underwater mountains. The map, presented in the Oct. 3 Science, is the most accurate global seafloor map ever made and could provide new clues to how Earth’s surface got its shape.

“We know a lot about the continents, but we know almost nothing about what’s going on in the oceans,” says lead author David Sandwell, an earth scientist at the Scripps Institution of Oceanography in La Jolla, Calif. “It’s like being on another...

Creepy crawlers play key role in structure of grasslands -- ScienceDaily

The critical importance of earthworms, beetles, and other tiny creatures to the structure of grasslands and the valuable ecosystem services they provide has been outlined by researchers. "These findings emphasize how interconnected the belowground and aboveground components of ecosystems are and that different ecosystem processes respond in different ways to the management of grasslands," said a co-author of the study.
