attribute NC_GLOBAL acquisition_description String Methods description:
Between April 2014 and January 2015, discrete samples for total alkalinity
(TA), dissolved inorganic carbon (DIC), total organic carbon (TOC), and
nutrients (nitrate, nitrite, ammonium, phosphate, and silicate) were collected
hourly from high tide to low tide at the mouth of SDL, both during the day and
during the night. Samples for TA, DIC, and nutrients were also collected at
ten different sites across the SDL during the day at high tide. For all
samples collected, surface temperature, salinity, and dissolved oxygen were
measured with handheld YSI multiprobe while discrete seawater samples were
collected by hand at the surface following standard protocols.

Analytical Methods:
Surface seawater samples were collected by hand at ~0.25 m depth using 250
ml Pyrex glass bottles and immediately fixed with 100 \u00b5L HgCl2 as per
standard protocols (Dickson et al. 2007). A handheld YSI multiprobe Pro2030
was calibrated and used to measure temperature, salinity, and dissolved oxygen
saturation at the time of sampling. All seawater samples were transported to
the Scripps Coastal and Open Ocean Biogeochemistry lab and analyzed for TA via
an open-cell potentiometric acid titration system developed at Scripps
Institution of Oceanography (SIO) by A. Dickson (Dickson et al. 2007) and DIC
via an automated infra-red inorganic carbon analyzer (AIRICA, Marianda Inc).
Nutrient samples were filtered through a 0.45 um filter into acid-leached
HDPE-containers, and kept frozen until analysis. They were analyzed at
Oceanographic Data Facility at SIO
[(http://odf.ucsd.edu](\\"http://\(http://odf.ucsd.edu\\")) using a Seal
Analytical continuous-flow AutoAnalyzer. TOC samples were collected in
combusted glass-vial and acidified with trace-metal grade HCl. They were
analyzed in the Aluwihare lab at SIO according to Pedler et al. (2014) by
combusting an unfiltered sample and measuring CO2 gas concentration using a
non-dispersive infrared detector.

Quality Control:
Standard protocols were followed for sampling and analysis of seawater all
parameters. The YSI multiprobe was calibrated prior to each sampling with an
accuracy of \u00b10.2\u00b0C for temperature, \u00b10.3 g kg-1 for salinity,
and \u00b12% for DO. The mean accuracy (TA\u00b11 \u00b5mol kg-1, DIC \u00b11
\u00b5mol kg-1) and precision (TA\u00b12 \u00b5mol kg-1, DIC \u00b12 \u00b5mol
kg-1) of TA and DIC measurements were evaluated using certified reference
materials (CRM) provided by the laboratory of A. Dickson at SIO and analyzed
every 5 samples for DIC and ~10 samples for TA. The uncertainty of the
nutrient measurements were reported as nitrate \u00b10.05 uM, nitrite
\u00b10.05 uM, ammonium \u00b10.03 uM, silicate \u00b12-4 uM, and phosphate
\u00b10.004 uM by ODF. The TOC method was reported with an uncertainty of

attribute NC_GLOBAL instruments_2_dataset_instrument_description String The open-cell potentiometric acid titration system was developed by the laboratory of A.G. Dickson. Briefly, a known amount of seawater is added to an open cell temperature controlled beaker. Hydrochloric acid is added using a Methrom Dosimat to a pH of 3.5-4.0 and allowed to stabilize to remove CO2 gas formed by the addition of acid. Small aliquots of hydrochloric acid are then added to pH of ~ 3.0. The titration is monitored by a glass electrode and the total alkalinity of the sample is calculated using a non-linear least-squares method following Dickson et al. (2007).

attribute NC_GLOBAL instruments_3_dataset_instrument_description String The Automated Infra Red Inorganic Carbon Analyzer (AIRICA) utilizes infrared detection of CO2 gas purged from an acidified seawater sample. A high-precision syringe pump extracts the seawater sample, acidifies the sample with phosphoric acid, and analyzes the gas released with an infrared light analyzer (LICOR). The CO2 signal is integrated for each sample to quantify the total inorganic carbon for a given aliquot of seawater analyzed. Three aliquots and peak integrations are performed for each seawater sample and averaged to determine the dissolved inorganic carbon for each sample. Precision was typically ±1–2 µmol/kg for TA.

attribute NC_GLOBAL projects_0_acronym String Nearshore CO2
attribute NC_GLOBAL projects_0_description String NSF abstract:
Because of well-known chemical principles, changes in the CO2 chemistry of seawater in the open ocean as a result of rising atmospheric CO2 can be predicted very accurately. On the other hand, in near-shore environments, these projections are much more difficult because the CO2 chemistry is largely modified by biogeochemical processes operating on timescales of hours to months. To make predictions on how near-shore seawater CO2 chemistry will change in response to ocean acidification (OA), it is critical to consider the relative influence of net ecosystem production (NEP) and net ecosystem calcification (NEC), and how these processes might change in response to this major perturbation. Understanding how future OA will alter near-shore seawater CO2 chemistry and variability was identified as a major critical knowledge gap at the recent IPCC WG II/WG I workshop on impacts of ocean acidification on marine biology and ecosystems in January of 2011, and also at the International Ocean Acidification Network workshop in Seattle in June of 2012.
With funding from this CAREER award, a researcher at the Scripps Institute of Oceanography and his students will study how biogeochemical processes and the relative contributions from NEP and NEC modify seawater CO2 chemistry in near-shore environments influenced by different benthic communities under well characterized environmental and physical conditions, and how these processes might change in response to OA. The team will investigate a limited number of contrasting habitats in subtropical (reef crest, back/patch reef, lagoon, seagrass bed, algal mat) and temperate (kelp bed, inter- and sub-tidal, marsh) environments during summer and winter, employing a method that evaluates the function and performance of the carbon cycle of a system using a stoichiometric vector approach based on changes in total dissolved inorganic carbon (DIC) and total alkalinity (TA). These field studies will be complemented by controlled mesocosm experiments with contrasting and mixed benthic communities under different OA scenarios.
The project has two educational components: (1) developing a research-driven OA and biogeochemistry course based on inquiry-, experience-, and collaborative-based learning; and (2) working with the Ocean Discovery Institute (ODI) to engage individuals from a local underrepresented minority community in science through educational activities focused on OA, and also providing a moderate number of internships for high school and college students to engage in this research project.
Broader Impacts: This project will directly support one PhD student, one junior research technician, and two high school and college interns from underrepresented minorities (URM) each summer of the project. It will contribute to the education of 80 undergraduate and graduate students participating in the research based ocean acidification/biogeochemistry course offered four times throughout the duration of the project at SIO/UCSD. Education and curricular material on the topics of OA, including hands-on laboratories, classroom and field-based activities will be developed through the collaboration with the ODI and brought to hundreds of URM students and their teachers in the City Heights area, a community with the highest poverty and ethnic diversity in the San Diego region. This collaboration will enable URM students to directly engage in a rapidly evolving field of research that has high relevance at both the local and global scales. To ensure broad dissemination of this project and the topic of OA, the research team will work with the Google Ocean team to incorporate information and educational material in the Google Ocean Explorer.
