title: Dissolved inorganic carbon, total alkalinity, pH on total scale, and other variables collected from discrete samples and profile observations during the R/V F. G. Walton Smith cruise WS24205 (EXPOCODE 33WA20240723) in the North Atlantic Ocean, Gulf of Mexico from from 2024-07-23 to 2024-07-30 (NCEI Accession 0298978)

description: Near-shore estuarine and coastal regions are where most recreational fishing and tourism occur, yet they are vastly under-sampled. Their susceptibility to OA is not well understood due to their high biogeochemical variability. These regions are affected by land-side processes such as river discharge and run-offs and ocean-side processes through slope water exchange. A full determination of the carbonate system in these regions in conjunction with open ocean measurements is needed to increase our understanding of the effects of OA on ocean health and fisheries and our ability to predict them. In this project, we propose to augment several observational campaigns by 1) adding a carbonate component to the harmful algal blooms (HABs) monitoring cruises conducted periodically on the Western Florida Shelf in order to study potential links between HABs and OA, 2) renewing our collaboration with select National Parks to complement and enhance our near-shore data collection on the Northern Gulf of Mexico and US East Coast, and 3) complementing our underway surface pCO2 measurements in the Gulf of Mexico and US East Coast with underway total alkalinity measurements to help us improve our fundamental understanding of nearshore OA processes. The addition of these measurements to the current assets already present in the region would enhance our understanding of the linkage between nearshore and open ocean processes and better assess the mechanisms and impacts of OA on the biogeochemistry, biology and their economic consequences.

title: AOML_ET: Partial pressure of CO2 (pCO2) and sea-air CO2 fluxes for the global ocean, along with the predictor variables from 1998-01-01 to 2023-12-30, using an Extra Trees (extremely randomized trees) machine learning (NCEI Accession 0298989)

description: This dataset contains global surface water partial pressure of CO2 data, pCO2w data, and sea-air CO2 fluxes based on the extremely randomized trees or extra trees, ET machine learning approach. The products are labeled as AOML_ET. The outputs are monthly pCO2 and sea-air CO2 flux fields at 1°x1° resolution covering the global ocean from 1998 to 2023. The results of several different permutations of AOML-ET are provided. They all use the following predictor variables at monthly and at 1°x1° resolution. The variables are time, location, sea surface temperature, SST, sea surface salinity, SSS, mixed layer depth, MLD, and chlorophyll-a, chl-a. The training is performed on the v2020 and v2023 releases of the Surface Ocean CO2 Atlas (www.SOCATinfo). The sea-air CO2 fluxes are computed from the air-sea CO2 partial pressure difference, ∆pCO2, and a bulk gas transfer formulation with windspeed. This data holding includes files of the monthly 1°x1° predictor variables. Several AOML_ET products are provided in this accession. SOCATv2020 and SOCATv2023 are used for training; pCO2w and ∆pCO2 are target variables; two different datasets for air CO2 are used for the calculation of sea-air CO2 fluxes, and three different gas exchange parameterizations are applied to determine the sea-air CO2 fluxes. Details are found in the readme file.

title: Progression of Ocean Interior Acidification over the Industrial Era from 1800-07-01 to 2014-06-30 (NCEI Accession 0298993)

description: This dataset consists of time-resolved reconstructions of ocean interior acidification from 1800 through 1994, 2004, and 2014. The basis of these reconstructions are observation-based estimates of the accumulation of anthropogenic carbon, combined with climatologies of hydrographic and biogeochemical properties in the ocean interior. Acidification trends are determined for several parameters of the marine CO2 system, namely the saturation state of aragonite (Ωarag), the carbonate ion concentration ([CO32-]), the free proton concentration ([H+]), and pH on the total scale (pHT). The underlying anthropogenic carbon concentration (ΔCant), the computed sensitivities of the four marine CO2 system parameters and their absolute state estimates are provided as well. The datasets contain in addition to the standard estimate also 14 sensitivity cases, which are intended to assess the robustness of our acidification estimates to changes in the estimation procedure of ΔCant as well as the climatological distributions of other hydrographic properties. All estimates are provided on a horizontal grid with 1° x 1° resolution and for 28 depth layers from 0 - 3000m. These data provide strong constraints on ocean interior acidification over the industrial era, unravelling in particular its progression since 1994.

title: Blue mussel fertilization to early juvenile development under ocean acidification for 5 populations from Long Island Sound from 2017-04-20 to 2017-06-04 (NCEI Accession 0299732)

description: This dataset contains laboratory experimental data of blue mussels (Mytilus edulis) exposed to three different levels of carbon dioxide (low, mid, and high) from 4 hours post fertilization to day 45. Blue mussels were collected from 4 different populations located in Long Island Sound. The experiment took place from April 20, 2017 to June 4, 2017 at the NOAA NEFSC in Milford CT, with seawater pumped from Milford Harbor to the laboratory (41° 12′ 42.46″ N, 73° 3′ 7.75″ W). Carbonate chemistry and survival of blue mussels from the larval stage to the juvenile stage were assessed. This effort was made possible through the project R/XG-25 under the award NA14OAR4170069 from the National Sea Grant College Program of the US Department of Commerce’s National Oceanic and Atmospheric Administration .

title: Water temperature, salinity, total alkalinity, pH, partial pressure of CO2 (pCO2), and calcite saturation measured using water samples collected at the Mukilteo Research Station located in the Puget Sound, WA from 2018-08-26 to 2019-07-11 (NCEI Accession 0300467)

description: This dataset contains the seawater chemistry monthly means with standard deviations measured using water samples collected at the Mukilteo Research Station located in the Puget Sound, WA from 2018-08-26 to 2019-07-11. Water temperature (°C) is from the average of all 4 Durafet pH sensors deployed in the experimental tanks. Salinity data are from periodic measurements taken of all 6 experimental tanks use a hand-held Orion salinity sensor. The ambient and high-CO2 pH values are spectrophotometric pH averages from all treatment tanks. Alkalinity was calculated from the salinity values using the functional relationship in (Trigg et al., 2019). The pCO2 and calcite saturation state values were calculated using the SeaCarb R package (Gattuso et al., 2021) with the spectrophotometric pH and calculated alkalinity values as carbonate system parameter inputs. No spectrophotometric pH or Orion salinity data were recorded for January because a U.S. Government shutdown prevented collection of these data. However, automated pH and salinity sensors operating in the experimental tanks during January indicate that interpolation by averaged data from December and February, is a reasonable approximation.

title: Synthesizing the Impacts of Ocean Acidification on Coral Reef Ecosystem Goods and Services for Future Vulnerability Assessments using an Atlantis Ecosystem Model from 2020-01-01 to 2020-12-31 (NCEI Accession 0300557)

description: The files described here are the Main Hawaiian Islands (MHI) Atlantis Ecosystem model input files used in for testing CMIP6 climate scenarios developed by main Hawaiian Islands ROMS. These input files were used to run forecast simulations under three different CMIP6 climate change scenarios: low-emission (SSP1-2.6), moderate-emission (SSP2-4.5), and high-emission (SSP3-7.0). Files included are parameter (.prm), initial conditions (.nc), and land-based source pollutants (LBSP) forcing files. The parameter files include a run file, biological parameters, forcing parameters (list climate and pollution forcing files), harvest parameters (fishing mortality), and physics parameters. The LBSP forcing files are time series files representing spatial deposition of nutrients and sediments from land to the nearshore regions covered by Hawaii Atlantis. In recalibrating the current model based on updated climate forcing files (ROMS projections), the parameter and initial conditions files have been adjusted since initial model development. The ROMS projections used to force Hawaii Atlantis are not included in this data set, as they are from a different project.

Hawaii Atlantis was initially developed at PIFSC and further details regarding the model, as well as outputs of a model run based on older inputs, are hosted as InPort catalog item 55245. The LBSP forcing files hosted here were developed based on Ocean Tipping Points project data as part of initial model development.

Lat. -78.201138 Lon. 3.0163611; 2. Lat. -78.221416 Lon. 2.9705833; 3. Lat. -78.163861 Lon. 2.9960278; 4. Lat. -78.101555 Lon. 2.9473889; 5. Lat. -78.101555 Lon. 2.9322222; 6. Lat. -78.122865 Lon. 2.8756667; 7. Lat. -77.979865 Lon. 2.7204915. The measurements were taken with two CTD divers (SonTek CastAway-CTD and Eijkelkamp CTD-Diver 11.11.60) and one Niskin bottle (5L). The water samples where taken to a oceanography lab in the Pontifical Xavierian University to be tested for total alkalinity (TA), and to the Autonomous University of Baja California for Dissolved Inorganic Carbon (DIC) measurements. This was done in order to calculate the carbon fluxes on a monthly scale throughout nine months during the 2021-2022 La Niña year for the whole study site, allowing for observations in the spatiotemporal flux behavior variability (shown in dataset as fco2_measured).

title: Hales_Kavanaugh Remote-sensing-based SOM and Carbonate-system Metamodel from 2009-01-01 to 2009-12-31 (NCEI Accession 0301441)

description: The model is based on a semi-mechanistic model of total CO2 (TCO2) and alkalinity, applied within regions defined hierarchical SOM classification of monthly-resolved seascapes along the North American Pacific coast, constrained by reproduction of coastal pCO2 observations as provided by Takahashi. This follows the Hales et al. 2012 approach, improved by the monthly-resolved dynamic seascape approach of Kavanaugh et al. The improvements allow coverage from Vancouver Island to Panama, with only a marginal increase in the number of seascapes over that limited in southern extent to Baja California Sur. The model domain is from 5° N to 50° N, and within 200 nm of the coastline. The result is further enhanced by employing the intermediate, pCO2-constrained TCO2 and Alk product to generate predictions of pH and the saturation state of the CACO3-mineral aragonite.

title: Portland Harbor Benthic Invertebrate Growth and Survival 2004 - 2007 (NCEI Accession 0301784)

description: The lower Willamette River, between Willamette Falls and the confluence with the Columbia River, in Portland, Oregon has a long history of industrialization and contamination. The river has supported a major commercial shipping port and industrial waterfront for over a century. As part of this industrialization, numerous industries have released toxic contaminants into the waterway over decades. These pollutants include polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its derivatives (DDT), polycyclic aromatic hydrocarbons (PAHs), and metals. As part of a Natural Resource Damage Assessment (NRDA) addressing historical pollution at the designated Superfund site the National Oceanic and Atmospheric Administration (NOAA) reevaluated data from the risk assessment to advance the understanding of the magnitude of impacts to benthic invertebrates exposed to a mixture of contaminants in the Superfund site through the application of principal components analysis, mean probable effects quotients (mPEC-Qs), and dose response curves.
