FSU researcher deep-sea coral reef depths of North Pacific
2017/7/25
Scientists have long believed that the waters of the Central and Northeast Pacific Ocean were inhospitable to deep-sea scleractinian coral, but a Florida State University professor’s discovery of an o...
Low-oxygen 'dead zones' in North Pacific linked to past ocean warming
Low-oxygen dead zones North Pacific ocean warming
2015/12/7
A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic, conditions that led to vast marine dead zones.Results of the re...
Formation of coastal sea ice in North Pacific drives ocean circulation and climate
coastal sea ice North Pacific ocean circulation and climate
2015/11/12
An unprecedented analysis of North Pacific ocean circulation over the past 1.2 million years has found that sea ice formation in coastal regions is a key driver of deep ocean circulation, influencing ...
Most descriptions of sounds produced by whales at sea have been described from scattered, unsystematic observation and recording of animals during shipboard encounters. Such encounters provide data on...
Exploration for Deep-Sea Corals on North Pacific Seamounts and Islands
North Pacific Seamounts Islands
2015/7/22
Seamounts are mountains that rise from the seafloor. The technical geological definition of a seamount is a steep-sided feature with greater than 1000 m of relief compared to the surrounding sea botto...

Midwater zooplankton and suspended particle dynamics in the North Pacific Subtropical Gyre: A stable isotope perspective
North Pacific Subtropical Gyre Midwater zooplankton
2014/4/2
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13
CAA values) of midwater
zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...
