The Madden-Julian Oscillation (MJO) is the leading intraseasonal (20–100 days) variability in the tropics. It affects many weather-climate phenomena globally. Tremendous progress has been made in observing, describing, simulating, understanding, and...

The Washington/Oregon shelf, embedded in the Northern California Current System, is a productive habitat with important commercial fisheries. One of the most valuable species is Dungeness crab, which resides on the subsurface shelf and is sensitive...

Ocean warming absorbs about 9/10th of the excess energy that is entering Earth’s climate system because of a build-up of man-made greenhouse gasses in the atmosphere. That warming causes ocean expansion, contributing to sea level rise. Knowing how...

The magnitude 7.0 Haiti earthquake of 2010 ruptured a complex fault network including both strike-slip faults (where two blocks slide past one another) and reverse faults (in which the upper block, above the fault plane, moves up and over the lower...

With annual revenues up to $220 million, the Dungeness crab (Metacarcinus magister) is one of the most valuable commercial fisheries on the US West Coast. Yet, rapid intensification of ocean acidification (OA) along the US West Coast is reducing...

The sei whale is a large baleen whale, in the same genus as the blue whale, found in most of the world's oceans outside the Arctic. From 2009 to 2014, we searched acoustically for sei whales off the northeast coast of Greenland on the edge of the...

Wave-breaking at the ocean surface transports pockets of air from the atmosphere into the upper few meters of the ocean. This air forms bubbles and as these bubbles rise to the ocean surface they pick up organic compounds associated with ocean...

A new study published in the journal Nature (Roxy et al., 2019) shows that warming of the Indo-Pacific Ocean is altering rainfall patterns across the globe, contributing to declines in rainfall along the U.S. West Coast and parts of the East Coast...

OceanObs’19 was held in Honolulu, Hawaii, in September 2019. The conference presented a unique forum to share new ideas and concepts in marine data management and to emphasize the opportunities presented by a rapidly changing technology landscape...

Fluids in the Earth’s crust are heated by magma rising to the seafloor where tectonic plates separate or collide. These discharging fluids cool hot rock, construct mineral deposits, nurture biological communities, alter deep-sea mixing and...

With the ability to transit thousands of kilometers while making surface observations similar to a moored buoy, the unmanned surface vehicle (USV) Saildrone, manufactured and piloted by Saildrone, Inc., could contribute in important ways to the...

About half of carbon emissions are currently absorbed by natural processes taking place on land and in the ocean. But not all regions of the Earth’s surface act as a sink for emitted CO₂. The tropical Pacific Ocean stands out as a significant source...

In 2014-2016, a marine heat wave, also known as the Blob, produced abnormally warm waters off the US West Coast and in the Gulf of Alaska. Temperatures in the upper 100 meters of the ocean were more than 2.5° C higher than the long term (1981–2010)...

About 80% of volcanic activity on Earth occurs on the deep seafloor of the global ocean. These eruptions are concentrated where the Earth’s tectonic plates collide or separate, accelerating the transfer of heat, chemicals, and microbes from the crust...

Due to naturally cold, low carbonate concentration waters, the Bering Sea is highly vulnerable to ocean acidification (OA), the process in which the absorption of human-released carbon dioxide by the oceans leads to a decrease in ocean water pH and...

It’s unclear when the human fascination with the voices of humpback whales began, but with the release of the album “Songs of the Humpback Whale” in 1970, humpbacks became arguably the most listened to whales in the world. But humpback whales do more...
