Ocean breathability key to past future habitat West Coast marine species
2020/6/5
Marine species off the west coast of North America from Mexico through Canada inhabit the California Current. The cool, nutrient-rich water supports marine life ranging from invisible phytoplankton to...

Marine species off the west coast of North America from Mexico through Canada inhabit the California Current. The cool, nutrient-rich water supports marine life ranging from invisible phytoplankton to...
There's no longer a need to guess what ocean temperatures were like in the remote tropical Pacific hundreds of years ago. The ancient coral that lived there tells the tale, say National Science F...
Mollusk graveyards are time machines to oceans' pristine past
Mollusk graveyards time machines oceans pristine past
2017/3/14
A Florida Museum of Natural History study shows that mollusk fossils provide a reliable measure of human-driven changes in marine ecosystems and shifts in ocean biodiversity.Collecting data from ...
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...
In this issue of Oceanography, the majority of the papers presented focus on the harmful health effects of the oceans created by oceanic events, anthropogenic influences, and harmful marine life. Thes...
Oceans Past:Management Insights from the History of Marine Animal Populations
Oceans Past Management Insights Marine Animal Populations
2015/7/22
If we could be transported back through time, would we recognize the structure of ocean ecosystems through the prism of their current state? What have we lost and to what degree might we be able to re...
Chemoautotrophy at Deep-Sea Vents:Past,Present,and Future
Deep-Sea Vents Past Present Future
2015/7/14
Chemolithoautotrophic microorganisms are at the nexus of hydrothermal systems by effectively transferring the energy from the geothermal source to the higher trophic levels. While the validity of this...
Variable effects of marine-derived nutrients on algal production in salmon nursery lakes of Alaska during the past 300 years
marine-derived nutrients algal production salmon nursery lakes Alaska during the past 300 years
2014/4/22
We measured historical changes in sedimentary δ15N and fossil pigments in four lakes with anadromous semelparous salmon and two reference lakes to quantify the degree to which the flux of marine-deriv...
CO2 control of Trichodesmium N2 fixation, photosynthesis, growth rates, and elemental ratios: Implications for past, present, and future ocean biogeochemistry
CO2 control Trichodesmium N2 fixation photosynthesis growth rates elemental ratios past present future ocean biogeochemistry
2014/4/22
Diazotrophic marine cyanobacteria in the genus Trichodesmium contribute a large fraction of the new nitrogen entering the oligotrophic oceans, but little is known about how they respond to shifts in g...
