chlorophyll a estimates from Niskin bottle casts Dataset Description: <p>Fluorometric chlorophyll a estimates from Niskin bottle cast samples</p> Methods and Sampling: <p>NOTE: station 1- or 2- refers to either cruise leg 1 (Florida to the Azores) or cruise leg 2 (Azores to Iceland)</p>
<p>Only 'surface' samples were taken while dead-heading on leg 1. The surface samples are recorded as being from nominal depth of 3 meters as that was the approximate depth of the ship's underway intake system.</p>
<p><strong>Calibration notes</strong> <br>
Instrument was calibrated prior to the cruise (~ May 1, 2005) using extracted chlorophyll a standards. <br>
Extracted standards were checked with a spectrophotometer to determine chlorophyll a concentrations. <br>
Extracted standards were used to calibrate the solid standard (Turner Designs). <br>
Solid-standard normalizations were completed each day upon initiation of the fluorometer.</p>
<p>Size-fractionated chl a concentrations were determined on replicate samples collected on 0.22, 2.0, and 20.0 um nominal pore size, 47 mm diameter polycarbonate filters (Osmonics). Samples were extracted in 90% acetone for 24 h at 4&#0176;C and quantified using a solid-standard normalized 10-AU field fluorometer (Turner Designs) using the nonacidification protocol (Welschmeyer 1994). </p>

North Atlantic Spring Bloom 2005
<p>Climate-related shifts in phytoplankton assemblages may have profound implications for oceanic feedbacks on the atmosphere, and for human use of marine resources. Particular algal groups are largely responsible for crucial processes like vertical carbon export, biogenic calcification and silicification, production of climatically active gases like dimethylsulfide (DMS), and for sustaining food webs that lead to economically valuable higher trophic levels. The North Atlantic Spring Bloom 2005 (NASB 2005) research program was designed to investigate potential climate change impacts on algal community structure and biogeochemistry during the North Atlantic Spring Bloom, a regime that is ideal for determining how changing ocean conditions may affect both calcareous and siliceous algae. </p>
<p>
The research was coordinated with CarboOcean, a major European Union funded activity led by investigators from the Alfred Wegener Institute. </p>
