The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | NCCOS Assessment: Baseline Chemical Contaminants Data from the Nuuuli Pala Lagoon, American Samoa from 2017-07-11 to 2017-07-14 (NCEI Accession 0208106) |
| Abstract: | This dataset represents a one-time sediment sampling effort from the Nu’uuli Pala Lagoon, American Samoa. A suite of organic and inorganic parameters were quantified at twelve randomly selected sites and one targeted site in 2017, including: polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), pesticides, human-use pharmaceuticals and personal care products, trace elements, carbon, Clostridium perfringens abundance, and sediment grain size. |

| Supplementary information: | Methods: Three strata were delineated within the Lagoon based on geography. Within each strata, four sites were randomly selected (using ArcGIS) in order to capture the spatial variability within the Lagoon. This stratified random sampling design allows for statistical comparisons among the articulated strata. Additionally, one targeted site was selected at the direction of our partners, adjacent to a construction site at the south end of Lion’s Park (site TS-1, on the east side of the Lagoon). Sites were accessed by sea kayak. Nitrile gloves were worn and certified pre-cleaned jars were used to minimize the potential for contamination or cross contamination between sites. In an effort to quantify loading of land-based sources of pollution entering the Pala Lagoon, surface salinity was measured using a hand-held refrac¬tometer at each sediment collection site. Samples were labelled and placed on ice in a cooler until they could be transferred to a freezer at the conclusion of each sampling day. A subset of each sample was placed into a Whirl-pak™ bag for Clostridium perfringens and grain size analysis and refrigerated upon the conclusion of each sample day. Samples were shipped under chain-of-custody and arrived in good condition to TDI Brooks International in College Station, TX for analytical services. All laboratory analysis were per¬formed using protocols from the NS&T Program by TDI-Brooks, International or their subcontractor, AXYS Analytical. Detailed descrip¬tions of NS&T protocols, including quality assurance/quality control (QA/QC) and analytical methods used can be found in Kimbrough et al., 2006. Laboratory analysis methods specifically for AXYS related analytical results (current use pesticides and human use pharmaceuticals) are proprietary and confidential. The method names used for this study were MLA-035 REV.07.04 and MLA-070 REV.07.04.
