Sea ice kept oxygen from reaching deep ocean during last ice age, study finds

Extensive sea ice covered the world’s oceans during the last ice age, which prevented oxygen from penetrating into the deep ocean waters, complicating the relationship between oxygen and carbon, a new study has found.

Neighbors influence coastal landowners’ decisions to armor shorelines against erosion, rising seas

Neighbors play an influential role in private oceanfront landowners’ decisions to protect their shorelines from erosion and rising sea levels, which could lead to excessive armoring of the coastline, a new analysis from Oregon State University shows.

Use of ocean resources changed as Dungeness crab fishing industry adapted to climate shock event

An unprecedented marine heat wave that led to a massive harmful algal bloom and a lengthy closure of the West Coast Dungeness crab fishery significantly altered the use of ocean resources across seven California crab-fishing communities.

Hormone metabolites found in poop give researchers new insight into whale stress

Poop samples are an effective, non-invasive tool for monitoring gray whale reproduction, stress and other physiological responses, a new study from Oregon State University shows.

No poaching occurring within most Channel Islands marine protected areas, new analysis shows

Fish are thriving and poachers are staying out of marine protected areas around California’s Channel Islands, a new population analysis by an Oregon State University researcher shows.

Shifts in water temperatures affect eating habits of larval tuna at critical life stage, study finds

Small shifts in ocean temperature can have significant effects on the eating habits of blackfin tuna during the larval stage of development, when finding food and growing quickly are critical to long-term survival.

Oregon State to manage cyberinfrastructure for the Ocean Observatories Initiative

Oregon State University will assume management of the data transmission cyberinfrastructure for a national initiative that monitors ocean conditions in real time, OSU and Woods Hole Oceanographic Institution announced today.

Ice discharge in the North Pacific set off series of climate events during the last ice age, study finds

Repeated catastrophic ice discharges from western North America into the North Pacific contributed to, and perhaps triggered, hemispheric-scale changes in the Earth’s climate during the last ice age, new research published online today in Science reveals.

Vessel noise present year-round at Cordell Bank National Marine Sanctuary near San Francisco

The environment in the Cordell Bank National Marine Sanctuary off the coast of San Francisco is not a refuge from the noise generated by ship traffic, the first underwater marine acoustic study of the region has shown.

Discovery of first active seep in Antarctica provides new understanding of methane cycle

The discovery of the first active methane seep in Antarctica is providing scientists new understanding of the methane cycle and the role methane found in this region may play in warming the planet.
