Carbonate chemistry analyses of seawater samples from zooplankton hatching experiments. Dataset Description: <p>Previous version date: 2012.12.06</p>
<p>Updated files and metadata from J. Christensen sent on 2015.05.26:</p>
<p>Previous file has been removed and metadata has been updated to reflect new report content. The following text is an excerpt from the summary included in the <em>Technical Report #15-009 linked under 'Acquisition description':</p>
<p>Experiments were conducted to test whether reduced pH of the ocean waters would negatively affect the hatching success of several zooplankton species found in northern ocean waters. These experiments were performed at the Darling Marine Center of the University of Maine, using local seawaters (salinities &gt; 30). Each experiment consisted of incubating fresh zooplankton eggs in several 20L seawater tanks at constant temperature for periods of up to 6 days. Each tank was maintained at fixed pH, and each experiment consisted of several tanks which covered a range of pH values at and below that of natural seawater. The measure of hatching success was the number of nauplii which were produced from the total number of incubated eggs. During the incubation, waters were extracted to measure carbonate system parameters and other key concentrations (titration alkalinity, total carbon dioxide, salinity, nitrate plus nitrite, ammonium, inorganic phosphate, and dissolved silicate), which were used to calculate the real pH of seawater in the incubation tanks. In addition, a ten day cruise covering the Gulf of Maine was taken in 2012 for the purpose of determining the distribution of carbonate species and pH in these waters. Analysis of these chemistry samples was performed at the Green Eyes LLC laboratory.</p> Methods and Sampling: <p>The following text is an excerpt from the <em>Technical Report #15-009,</em> linked below:</p>
<p>The details of the preparation and execution of the hatching experiments are being described in reports in preparation (Preziosi, 2012; Preziosi et al., 2012, 2013; Preziosi, Runge, Christensen and Jones, in prep.). In brief, female zooplankton, freshly caught or reared in the lab with plentiful food, were maintained in a healthy condition and their released eggs separated. When the numbers of eggs required in an experiment were sufficient, the eggs were sorted into individual hatching dishes, each containing natural seawater and 30 eggs. Local seawaters were collected, filtered and used to fill several 20 L hatching tanks. Each tank was consisted of a polycarbonate tank and lid, and an aeration tube into which was bubbled a premixed gas, consisting of 20% oxygen, the preselected concentration of CO2 (ranging from ambient local atmospheric levels to 50000 ppm in the dry gas), and the remainder nitrogen gas (N2). A siphon mounted within the tank allowed for sampling of the waters without opening the tank. A 1-inch diameter hole in the tank lid, normally stoppered, allowed for immersion of the pH and temperature electrodes occasionally throughout the incubation. After the pH stabilized to its quasi-equilibrium value for the bubbled gas, several hatching dishes containing the eggs were immersed in the tank. The tank was closed and hatching allowed to proceed. At an appropriate time, all hatching dishes were removed for determination of hatching success and the experiment then ended. During the incubation, either once (for incubation times less than 2 days) or twice, at the beginning and near the end of the longer 4-6 day experiments, about 2 liters of tank water were withdrawn for collection of the chemistry samples, as described below. The chemical results were used to determine the tank's pH. P-3&nbsp;<br />
At each sampling event during hatching experiments, about 2 L of the tank waters were siphoned for samples of salinity, titration alkalinity (TA), total carbon dioxide (TCO2), and nutrients. All bottles for TA, TCO2, and nutrients had been previously acid cleaned and dried. Nevertheless, all bottles were rinsed four times with tank water prior to filling. Salinity was stored in tightly capped 0.5 L bottles at room temperature for later measurement. TA and TCO2 samples were drawn in a manner identical to the collection of dissolved oxygen samples. An air bubble of about 1% of the volume of the bottle was left in the top of the bottle and 0.10 ml of a 0.100 mole-Hg/L solution of HgCl2 was added as preservative, yielding a mercury concentration of about 100 μmol/L dissolved in the sample. The sample bottles were tightly capped and stored at room temperature until measurement. Nutrients were collected in plastic vials and frozen at -20°C until analyzed. The temperature of the cold room in which the experiment was being conducted was monitored continuously. All concentrations are reported relative to the weight of the final solution (kg of solution).&nbsp;<br />
In addition to the hatching experiments, we sampled the offshore waters of the Gulf of Maine during a 10-day cruise in autumn of 2012. Seawater was sampled using a vertically profiling CTD with rosette containing 24 30-liter Niskin water sampling bottles. collected. These CTD casts collected waters from the seasurface to within a few meters of the seafloor (depths as great as about 300 m). After the CTD/Rosette had returned from a cast, water from each Niskin was sampled for alkalinity, total carbon dioxide, dissolved oxygen (Carpenter et al., 1965), nutrients, and salinity. Alkalinity and TCO2 were sampled in a manner identical to the collection procedure used for Carpenter oxygen samples. Each alkalinity and total CO2 sample were preserved and stored as described for the hatching experiments. Nutrients and salinities were stored and measured identically to those from the hatching experiments.&nbsp;</p>

Ocean Carbon and Biogeochemistry
The Ocean Carbon and Biogeochemistry (OCB) program focuses on the ocean's role as a component of the global Earth system, bringing together research in geochemistry, ocean physics, and ecology that inform on and advance our understanding of ocean biogeochemistry. The overall program goals are to promote, plan, and coordinate collaborative, multidisciplinary research opportunities within the U.S. research community and with international partners. Important OCB-related activities currently include: the Ocean Carbon and Climate Change (OCCC) and the North American Carbon Program (NACP); U.S. contributions to IMBER, SOLAS, CARBOOCEAN; and numerous U.S. single-investigator and medium-size research projects funded by U.S. federal agencies including NASA, NOAA, and NSF.
The scientific mission of OCB is to study the evolving role of the ocean in the global carbon cycle, in the face of environmental variability and change through studies of marine biogeochemical cycles and associated ecosystems.
The overarching OCB science themes include improved understanding and prediction of: 1) oceanic uptake and release of atmospheric CO2 and other greenhouse gases and 2) environmental sensitivities of biogeochemical cycles, marine ecosystems, and interactions between the two.
The OCB Research Priorities (updated January 2012) include: ocean acidification; terrestrial/coastal carbon fluxes and exchanges; climate sensitivities of and change in ecosystem structure and associated impacts on biogeochemical cycles; mesopelagic ecological and biogeochemical interactions; benthic-pelagic feedbacks on biogeochemical cycles; ocean carbon uptake and storage; and expanding low-oxygen conditions in the coastal and open oceans.

Ocean Acidification-Category 1- Impact of ocean acidification on survival of early life stages of planktonic copepods in the genus Calanus in the northern
<p><em>The project description is a modification of the original NSF award abstract.</em></p>
<p>This research project is part of the larger NSF funded CRI-OA collaborative research initiative and was funded as an Ocean Acidification-Category 1, 2010 award. While attention concerning impacts of predicted acidification of the world's oceans has focused on calcifying organisms, non-calcifying plankton may also be vulnerable. In this project, the investigator will evaluate the potential for impacts of ocean acidification on the reproductive success of three species of planktonic copepods in the genus Calanus that are prominent in high latitude oceans. <em>C. finmarchicus</em> dominates the mesozooplankton biomass across much of the coastal and deep North Atlantic Ocean. <em>C. glacialis</em> and the larger <em>C. hyperboreus</em> are among the most abundant planktonic copepods in the Arctic Ocean. Previous research showed that hatching success of <em>C. finmarchicus</em> eggs was severely inhibited by increased CO2 and lower pH in seawater, but only tested at an extreme level. Preliminary results in the investigator's laboratory indicate that hatching success of <em>C. finmarchicus</em> is substantially reduced at increased seawater CO2 concentrations corresponding to pH levels between 7.9 and 7.5. Predictions of likely decline of surface pH levels to 7.7-7.8 over the next century raise questions about impacts on Calanus population dynamics if these preliminary results are confirmed. <em>C. finmarchicus</em>, for example, is presently at the southern edge of its range in the Gulf of Maine. The combination of higher surface layer temperature and lower pH may inhibit reproductive success during the late summer/fall bloom, which the PI hypothesize is critical to sustain the overwintering stock in this region. The investigators will collect <em>C. finmarchicus</em> females from the Gulf of Maine and, with the assistance of Canadian colleagues, <em>C. glacialis</em> and <em>C. hyperboreus</em> females from the deep lower St. Lawrence Estuary. They will conduct laboratory experiments in which hatching success, development and growth of Calanus nauplius stages are measured in controls of natural seawater and at a series of treatments in which CO2 concentrations, pH and temperature are rigorously controlled to represent possible future states of the northern ocean. The investigators will measure present surface and deep pCO2 and pH across the Gulf of Maine, including its deep basins, during a research cruise. The study will evaluate the hypothesis that predicted levels of CO2 increase in the northern ocean will impact population dynamics of the Calanus species. Using the results from the research cruise and a recently developed 1-D, Individual-Based life cycle model, the PI will explore in detail scenarios of impact of higher temperature and lower surface and deep pH on population dynamics of <em>C. finmarchicus</em> in the Gulf of Maine.</p>
<p>The lipid-rich Calanus species are considered key intermediary links between primary production and higher trophic levels in North Atlantic and Arctic Ocean food webs. Impacts of higher surface temperature and lower pH on reproductive success may potentially lead to profound changes in energy transfer and structure of pelagic ecosystems in the northern oceans. In the Gulf of Maine, <em>C. finmarchicus</em> serves as primary prey for herring, sand lance, and mackerel, as well as the endangered northern right whale, warranting thorough evaluation of ocean acidification effects on its population dynamics.</p>
