Research expedition faces extreme conditions in fast-changing Arctic（图）
Research expedition faces extreme conditions fast-changing Arctic
2020/4/26
In October 2019, scientists froze a ship filled with equipment into Arctic sea ice with the intention of drifting across the Arctic Ocean for a full year, gathering data on polar atmosphere, ic...
Researchers find new reason why Arctic is warming so fast（图）
new reason Arctic warming so fast
2020/2/28
The Arctic has experienced the warming effects of global climate change faster than any other region on the planet. Scientists at the Scripps Institution of Oceanography have developed a new theory ai...
Blue sharks use ocean eddies as fast-tracks to food（图）
Blue sharks ocean eddies fast-tracks food
2019/10/21
Blue sharks use large, swirling ocean currents known as eddies to fast-track their way to food in the twilight zone -- a layer of the sea between 200 and 1,000 meters deep, according to new research b...
Sardines,Anchovies and Other Fast-Growing Fish Species Vulnerable to Dramatic Population Plunges
Sardines Anchovies Other Fast-Growing Fish Species Vulnerable Dramatic Population Plunges
2015/8/13
A Rutgers marine biologist studying the rise and fall of fish populations worldwide recently made a counterintuitive discovery: ocean species that grow quickly and reproduce frequently, such as sardin...
Vertical Variations of Tidal Currents in Shallow Land Fast Ice-Covered Regions
Vertical Variations Ice-Covered Regions Tidal Currents
2009/1/4
Arctic tidal currents with periods near the local inertial period are strongest and rotate clockwise at mid-depth, and decrease in amplitude towards the bottom and ice-cover, experiencing a change in ...
On “Too Fast” Baroclinic Planetary Waves in the General Circulation
General Circulation Too Fast Baroclinic Planetary Waves
2008/10/27
Recent altimetric observations of the ocean surface reveal signatures of long planetary waves near the annual frequency band. Comparisons of the observed wave speeds and those predicted by standard li...
Fast direction of arrival algorithm based on vector-sensor arrays using wideband sources
acoustic vector sensor propagator method coherent processing fast algorithm
2011/9/14
An acoustic vector sensor (AVS) can capture more information than a conventional acoustic pressure sensor (APS). As a result, more output channels are required when multiple AVS are formed into arrays...
Biogas (CO2, O2, dimethylsulfide) dynamics in spring Antarctic fast ice
Biogas dynamics in spring Antarctic fast ice
2014/4/22
We studied the temporal variations of CO2, O2, and dimethylsulfide (DMS) concentrations within three environments (sea-ice brine, platelet ice-like layer, and underlying water) in the coastal area of ...
Fast growth and turnover of chironomid assemblages in response to stream phosphorus levels in a tropical lowland landscape
Fast growth turnover of chironomid assemblages
2014/4/23
We studied the response of a dominant primary consumer, larval Chironomidae (Diptera), to phosphorus (via a
microbial response) across eight detritus-based streams spanning a gradient in soluble reac...
Maximum photosynthetic efficiency of size-fractionated phytoplankton assessed by 14C uptake and fast repetition rate fluorometry
Maximum photosynthetic efficiency size-fractionated phytoplankton assessed 14C uptake fast repetition rate fluorometry
2014/5/13
Under high nutrient concentrations and sufficient light conditions, large phytoplankton may display higher photosynthetic efficiency than smaller cells. This is unexpected since smaller phytoplankton,...
Fast repetition rate fluorometry is not applicable to studies of filamentous cyanobacteria from the Baltic Sea
Fast repetition rate fluorometry studies of filamentous cyanobacteria the Baltic Sea
2014/5/19
Fast repetition rate (FRR) fluorometry has been used successfully to investigate the variable fluorescence characteristics of cyanobacteria in oceanic Case 1 waters. In these waters, the effective abs...

Assessing the error photosynthetic properties Fast Repetition Rate fluorometry
2014/5/22
Fast repetition rate (FRR) fluorometry is an optical technique for estimating photosynthetic properties of phytoplankton from measurements of variable fluorescence yield. I determined the minimum erro...
