Phytoplankton chlorophyll + nutrient studies Dataset Description: <h4>Phytoplankton Chlorophyll and Nutrient Studies<br />
on Georges Bank<br />

<h4><em>PROJECT OVERVIEW:</em></h4>
<p>The project began in the winter of 1997 as part of the <a href="http://globec.whoi.edu">U.S. GLOBEC Georges Bank Program</a>. The purpose of our component of that multi-institutional study is to investigate the idea that the growth and production of zooplankton and fish on Georges Bank are limited by the amount of nutrients (especially nitrogen) that is brought onto the Bank from the nutrient-rich, deeper waters around the Bank's edges (cf. Townsend and Pettigrew, 1997).</p>
<p>&nbsp;</p>
<p>The sampling period was chosen to bracket the winter-to-spring transition, which is coincident with the Georges Bank GLOBEC broad scale cruises conducted in 1997, 1998 and 1999. The cruise dates were:</p>

<p>Water samples were collected on all cruises for the analysis of phytoplankton biomass (chlorophyll a and phaeophytin). In addition, dissolved inorganic nutrient concentrations (NO3+NO2, SiO4, PO4 and NH4) were determined for four of the six Broadscale cruises in 1997, five of six in 1998, and all six in 1999. Water collections were made at various depths at all of the regular hydrographic stations (1-40 or Sta 41 after 1997) using Niskin bottles mounted on the rosette sampler. Additional surface water samples were collected at positions between the regular stations (numbered &gt;41; refer to <a href="http://globec.whoi.edu/images/station_locations_townsend.gif"> Station Location Map</a> for example). Note that because data files are in some cases ordered by station number, time does not necessarily increase monotonically throughout a given data file. Detection limits for ammonia vary for each month of analysis; for details contact Maura Thomas (mthomas@maine.edu) or David Townsend (davidt@maine.edu).</p>
<p>Phytoplankton chlorophyll a and phaeopigments were determined fluorometrically (Parsons et al., 1984). The extracted chlorophyll measurements involved collecting 100ml from all bottle samples taken at depths shallower than 60m, filtering through GF/F filters, and extracting in 90% acetone in a freezer for at least 12 hours. The samples were analyzed at sea using a Turner Model 10 fluorometer.</p>
<p>Water samples for DIN were filtered through 0.45 Millipore cellulose acetate membrane filters and then frozen immediately in 20ml acid-washed polyethylene scintillation vials by first placing the vials in a seawater-ice bath for approximately 10 minutes. Samples were analyzed in the lab following the cruise using a Technicon II 4-Channel Auto-Analyzer.</p>
<p>In addition to dissolved inorganic nutrients and chlorophyll, in 1999 we are also analyzing samples for particulate organic carbon and nitrogen, dissolved organic nitrogen, and particulate and dissolved organic phosphorus.</p>
<p>Results from the vertical profiles taken at each station can be viewed as contour plots (using Surfer Software, Golden Colorado) for <a href="http://grampus.umeoce.maine.edu/globec/globec97/globec97.htm">1997</a>, <a href="http://grampus.umeoce.maine.edu/globec/globec98/globec98.htm">1998</a> and <a href="http://grampus.umeoce.maine.edu/globec/globec99/globec99.htm">1999</a>. Plotted variables include Temperature and Salinity for the hydrographic data, Chlorophyll a for the pigment analyses and Nitrate plus Nitrite, Silicate, Ammonium and Phosphate for the inorganic nutrient analyses. The hydrographic data were contoured only for the surface(2m). The pigment and inorganic nutrient concentrations were contoured for the surface(2m), 20meter and 60 meter depths.</p>

U.S. GLOBal ocean ECosystems dynamics
U.S. GLOBEC (GLOBal ocean ECosystems dynamics) is a research program organized by oceanographers and fisheries scientists to address the question of how global climate change may affect the abundance and production of animals in the sea.
The U.S. GLOBEC Program currently had major research efforts underway in the Georges Bank / Northwest Atlantic Region, and the Northeast Pacific (with components in the California Current and in the Coastal Gulf of Alaska). U.S. GLOBEC was a major contributor to International GLOBEC efforts in the Southern Ocean and Western Antarctic Peninsula (WAP).

U.S. GLOBEC Georges Bank
<p>The U.S. GLOBEC <a href="http://globec.whoi.edu/globec-dir/about_georges_bank.html">Georges Bank</a> Program is a large multi- disciplinary multi-year oceanographic effort. The proximate goal is to understand the population dynamics of key species on the Bank - Cod, <a href="http://globec.whoi.edu/images/haddock103.07.gif">Haddock</a>, and two species of zooplankton (<a href="http://globec.whoi.edu/images/calanus-finmarchicus.html"><em>Calanus finmarchicus</em></a> and <a href="http://globec.whoi.edu/images/pseudocalanus.html"><em>Pseudocalanus</em></a>) - in terms of their coupling to the physical environment and in terms of their <a href="http://globec.whoi.edu/images/targetpp.gif">predators and prey</a>. The ultimate goal is to be able to predict changes in the distribution and abundance of these species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.</p>
<p>The effort is substantial, requiring broad-scale surveys of the entire Bank, and process studies which focus both on the links between the target species and their physical environment, and the determination of fundamental aspects of these species' life history (birth rates, growth rates, death rates, etc).</p>
<p>Equally important are the modelling efforts that are ongoing which seek to provide realistic predictions of the flow field and which utilize the life history information to produce an integrated view of the dynamics of the populations.</p>
<p>The U.S. GLOBEC Georges Bank <a href="http://globec.whoi.edu/globec-dir/EXCO.html">Executive Committee (EXCO)</a> provides program leadership and effective communication with the funding agencies.</p>

Niskin Bottle
Niskin Bottle
PI Supplied Instrument Name: Niskin Bottle PI Supplied Instrument Description:Niskin bottles mounted on the rosette sampler.
