Sentences with phrase «surface chlorophyll»

These events resulted in substantial ecological and economic impacts, including sustained loss of kelp forests, coral bleaching, reduced surface chlorophyll levels due to increased surface layer stratification, mass mortality of marine invertebrates due to heat stress, rapid long - distance species» range shifts and associated reshaping of community structure, fishery closures or quota changes, and even intensified economic tensions between nations.»

The euphotic zone was calculated from the mean surface chlorophyll concentrations using the Case I model of Morel and Berthon (1989), while the export depth was calculated by subtracting the euphotic zone depth from the water depth.

Not exact matches

On Earth, the plant pigment chlorophyll absorbs the most abundant and highest - energy colors that reach the planet's surface — red and blue, respectively — while reflecting green, giving vegetation its color.

«It hit me that we've been calculating chlorophyll profiles from surface measurements for more than thirty years, but we don't know what the depth profiles of other biogeochemically - important materials look like,» said Barney Balch, a senior research scientist at Bigelow Laboratory and lead author on the paper.

This is an important finding because current estimates of biological activity in surface waters of the ocean rely on instruments aboard satellites that measure the color of the sea surface, which changes along with levels of chlorophyll - a, an assessment that will miss blooms of other organisms, such as bacteria.

Satellite Imagery: Through ground stations located at Rutgers University and University of Delaware, we access research satellites providing a number of products including Sea Surface Temperature, Chlorophyll and Backscatter

Beginning with a large sheet of heavy paper, Van Tran draws with acrylics, spirulina, and chlorophyll until the surface is densely covered with green and gray lines that run from edge to edge.

On the other hand I am co-plotting, down to sub-annual timescales up to 3 or even perhaps 4 well defined physical parameters relating to both the sea surface (e.g. SST, chlorophyll a, surface leaving radiance), the immediate subsurface (e.g. diffuse attenuation of 490 nm light to approx 50 m depth) and atmospheric aerosol size e.g. AOT at 865 and 890 nm — all measured with modern, state of the art surface telemetry and remote sensing methods and simply looking for mechanistic links between these parameters on sub-annual timescales.

Over the ocean this includes: sea surface slope and surface current, significant wave height, wind speed and sea level from radar altimetry at about 10 km resolution: sea surface temperature under cloud free conditions from the infrared radiometer at about 300 m resolution; chlorophyll a and phytoplankton from the imaging spectrometer under cloud free conditions at about 300 m resolution.

These characteristics included morphometric, geographic, and historical properties of study reservoirs (i.e., depth, residence time, volume, surface area, age, and latitude), biologically significant water column solute concentrations (i.e., NO3 — , total phosphorus, and dissolved organic carbon), and metrics of ecosystem primary productivity (i.e., trophic status and mean or modeled surface water chlorophyll a concentrations; see the supplemental materials for a complete list of the tested variables).

Chlorophyll a and air temperature were significant predictors of CH4 emissions from reservoir water surfaces regardless of flux type (i.e., diffusive only, ebullitive only, diffusive + ebullitive; supplemental tables S4 and S5).

Multiple parameters of the surface layer can be retrieved from space and the most known are the chlorophyll - a and the...

Pursuant to the urgent need for this knowledge in U.S. waters of the western North Atlantic and Gulf of Mexico, we integrated aerial and shipboard cetacean surveys conducted by five scientific organizations over 23 years and linked them to environmental data relating to cetacean habitat, such as sea surface temperature and chlorophyll concentration, obtained from satellite remote sensing and ocean models.

«Measurements at a sea platform show that the ocean surface albedo is highly variable and is sensitive to four physical parameters: solar zenith angle, wind speed, transmission by atmospheric cloud / aerosol, and ocean chlorophyll concentration.»
