                            <gco:CharacterString>NSF Climate Research Investment (CRI) activities that were initiated in 2010 are now included under Science, Engineering and Education for Sustainability NSF-Wide Investment (SEES). SEES is a portfolio of activities that highlights NSF's unique role in helping society address the challenge(s) of achieving sustainability. Detailed information about the SEES program is available from NSF (https://www.nsf.gov/funding/pgm_summ.jsp?pims_id=504707).
In recognition of the need for basic research concerning the nature, extent and impact of ocean acidification on oceanic environments in the past, present and future, the goal of the SEES: OA program is to understand (a) the chemistry and physical chemistry of ocean acidification; (b) how ocean acidification interacts with processes at the organismal level; and (c) how the earth system history informs our understanding of the effects of ocean acidification on the present day and future ocean.

                            <gco:CharacterString>In late June 2008, the OCB Project Office sent out a call for participation in the Coastal Synthesis Activity as part of the North American Carbon Program (NACP) Interim Synthesis Activities. The objective of this activity is to stimulate the synthesis and publication of recent observational and modeling results on carbon cycle fluxes and processes along the North American continental margin.  The current state of knowledge of the magnitude, spatial distribution, and inter-annual variability of carbon sources and sinks in coastal waters is incomplete.  Thus, the goal of this activity is to synthesize individual, small-scale studies across broader spatial and temporal scales to improve quantitative assessments of the North American coastal carbon cycle.  Because the coastal oceans have important and complex linkages with terrestrial, atmospheric, and open ocean biogeochemical cycles, we encourage the participation of researchers focused on both organic and inorganic carbon, as well as nitrogen and phosphorous cycle topics related to carbon balance and related issues such as hypoxia impacts on continental margins.
Planning for the coastal synthesis activity was initiated during a breakout session  at the 2008 OCB Summer Science Workshop.  The proposed coastal synthesis activity is initially broken into five U.S. geographical sub-regions (Atlantic Coast, Pacific Coast, Gulf Coast, Arctic Coast, and Laurentian Great Lakes), with leads identified for each region.  Researchers were encouraged to consider ongoing projects and think about how those projects might relate to one or more of the regional syntheses. Additional information available at the NACP Web site (http://www.nacarbon.org/cgi-bin/working_groups/wg.pl) includes a list of active NACP Interim Synthesis activities and working groups. 
The majority of data sets uploaded for this project will be synthesis data sets, representing an integration of previously compiled data from the various sub-regions.

                            <gco:CharacterString>The AON is envisioned as a system of atmospheric, land- and ocean-based environmental monitoring capabilities--from ocean buoys to satellites--that will significantly advance our observations of Arctic environmental conditions.  AON is an integral part of the interagency U.S. government initiative--the Study of Environmental Arctic Change (SEARCH) program, an NSF initiative growing out of the International Polar Year (IPY) to improve observational capabilities in the Arctic and leave a long-term legacy for the benefit of science and society.  Data from the AON will contribute to scientific research leading to (1) increased knowledge and understanding of the regional and global causes and consequences of present-day environmental arctic change, (2) scenarios for and prediction of the course of future arctic change and its regional and global consequences, and (3) the development of adaptive responses to arctic change.
AON currently consists of 51 projects funded by the NSF Office of Polar Programs. The AON projects fall into the following SEARCH Implementation Plan categories: Atmosphere; Ocean and Sea Ice; Hydrology/Cryosphere; Terrestrial Ecosystems; and Human Dimensions.</gco:CharacterString>

&lt;p&gt;The investigators will assess ocean acidification in the western Arctic Ocean, using ship time that is currently scheduled for annual mooring turnarounds in the Beaufort Sea. On these cruises, in September of 2011-2013, the investigators will collect samples for measurement of carbonate system parameters, inorganic nutrients, dissolved oxygen, oxygen isotopes, and oxygen/argon ratios, as well as continuous underway measurements of dissolved oxygen, oxygen/argon ratios, and pCO2. These data will be used to gain insights and perspectives into the extent of ocean acidification in the western Arctic Ocean; the key physical, chemical, and biological processes influencing the saturation states of aragonite and calcite; and potential impacts to pelagic and benthic communities. Water column observations will be synthesized with data from the associated NSF AON (Arctic Observing Network)-funded mooring, including temperature, salinity, nitrate, oxygen, pCO2, and pH, as well as carbon and hydrographic data collected on other cruises in the region. During each field season the PI will travel to several native villages to discuss the potential impacts of ocean acidification at town meetings and in classrooms. The work will contribute to carbon cycle studies coordinated under a variety of science plans and implementation structures that aim to establish accurate estimates of carbon budgets and fluxes and the underlying mechanisms that regulate them.&lt;/p&gt;

&lt;br /&gt;
&lt;strong&gt;Total CO2:&lt;/strong&gt;&lt;br /&gt;
Total CO2 analysis was done at the Ocean Acidification Research Center at the University of Alaska Fairbanks with a Marianda Versatile Instrument for the Determination of Titration Alkalinity (VINDTA) 3C coupled with a coulometer (UIC, Inc.). The samples were standardized using Certified Reference Materials (CRMs) provided by Dr. A. Dickson of Scripps Institution of Oceanography. Each 250 mL sample was poisoned with 0.2 mL of mercuric chloride. CRM batch numbers and correction magnitude:&lt;br /&gt;
108 (2022.70 ± 0.45 µmol kg-1) and 112 (2011.09 ± 0.47 µmol kg-1)&lt;br /&gt;
Method Reference: Mathis et al., 2010; Dickson et al. 2007. Bates et al., 2001&lt;br /&gt;
Whole cruise CRM values varied by ± 7.04 µmol kg-1&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Alkalinity:&lt;/strong&gt;&lt;br /&gt;
Alkalinity was measured by an open cell, high precision potentiometric titration on a VINDTA (#19 and 34) instrument with a 250 mL sample. Whole cruise CRM values varied by ± 6.52 µmol kg-1 Method References: Mathis et al., 2010; Dickson et al. 2007. Bates et al., 2001&lt;/p&gt;

  Instrument Name: CTD Sea-Bird SBE 911plus Instrument Short Name:CTD SBE 911plus   Instrument Description: The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/</gco:CharacterString>
