FSU researcher makes deep-sea coral reef discovery in depths of North Pacific
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...
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...
Climate variation, carbon flux, and bioturbation in the abyssal North Pacific
Climate variation carbon flux bioturbation abyssal North Pacific
2014/4/17
We hypothesized that seasonal and interannual climate-mediated changesin particulate organic carbon (POC) flux would affect bioturbation and ultimately the sequestration of organic carbon in the deep ...
Alkaline phosphatase activity and regulation in the North Pacific Subtropical Gyre
Alkaline phosphatase activity regulation the North Pacific Subtropical Gyre
2014/4/17
Alkaline phosphatase (AP) activity (APA) was measured at several stations in the North Pacific Subtropical Gyre in July 2008, and in a series of nutrient addition experiments: nitrate plus ammonium (+...
Assessment of relative phosphorus limitation of Trichodesmium spp. in the North Pacific, North Atlantic, and the north coast of Australia
Assessment of relative phosphorus limitation of Trichodesmium spp. in the North Pacific North Atlantic the north coast of Australia
2014/4/21
Trichodesmium spp. is a colonial diazotrophic cyanobacterium that occurs in the oligotrophic tropics and subtropics. Because of its ability to fix atmospheric N2, it is likely to be growth limited by ...
Net community production in the deep euphotic zone of the subtropical North Pacific gyre from glider surveys
Net community production deep euphotic zone subtropical North Pacific gyre glider surveys
2014/5/16
Seagliders, deployed through most of 2005 in the subtropical North Pacific gyre, made measurements of temperature, salinity, and dissolved oxygen to quantify net community production (NCP) at Station ...
Assessing nutrient limitation of Prochlorococcus in the North Pacific subtropical gyre by using an RNA capture method
nutrient limitation Prochlorococcus the North Pacific subtropical gyre RNA capture method
2014/4/21
It has been hypothesized that the planktonic community of the North Pacific subtropical gyre (NPSG) underwent a "domain shift" in the early 1980s in which phytoplankton of the domain Eukarya were supp...
Interactive influences of iron and light limitation on phytoplankton at subsurface chlorophyll maxima in the eastern North Pacific
Interactive influences of iron light limitation phytoplankton subsurface chlorophyll maxima eastern North Pacific
2014/4/18
The roles of iron and light as limiting and colimiting factors for phytoplankton growth in subsurface chlorophyll maxima (SCMs) were investigated in mesotrophic to oligotrophic waters of the Southern ...

Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean
Nitrogen fixation unicellular diazotrophic cyanobacteria temperate oligotrophic North Pacific Ocean
2014/4/22
N2 fixation has been understudied in marine environments outside of the subtropical and tropical oceans and where water temperatures are typically below 20-25°C. We identified nifH phylotypes and meas...

bacterial community structure light carbon cycling eastern subarctic North Pacific
2014/5/19
Biogeochemical controls on the community structure of heterotrophic marine bacteria are not well understood, and these organisms play a critical role in the global carbon cycle. Through terminal restr...
