Polycyclic aromatic hydrocarbons (PAHs) in the San Lorenzo River, Santa Cruz, California, USA, from 2015 to 2016
Polycyclic aromatic hydrocarbons (PAHs) are reported for water samples collected from the San Lorenzo River water during the rainy seasons from 2015 to 2016. Samples were collected during 2-, 5- and close to 10 year flood events.
Levels of Persistent Organic Pollutants Found in Blue Mussels (Mytilus trossulus) in the Aleutian Archipelago and Southeast Alaska in 1994-1996
The data consist of levels of organic pollutants found in the blue mussels (Mytelus trossulus) samples from 44 sites along the Aleutian archipelago and in Cross Sound in southeast Alaska. For each site, the percent lipid, percent water and the sum of the target organic compounds are reported. The compounds are PCBs (polychlorinated biphenyls), DDTs (dichlorodiphenyltrichloroethanes), HCHs (hexachlorocyclohexanes), chlordane, and HCB (hexachlorocyclobenzene).
Suspended sediment concentration (SSC) in the San Lorenzo River, Santa Cruz, California, USA, from 2008 to 2019
Suspended-sediment concentrations are reported in mg/L for water samples collected from the San Lorenzo River during the rainy seasons from 2008 to 2019. Samples were collected during 2-, 5- and 10-year flood events.
Surface runoff and submarine groundwater discharge in particular are known vectors to the coastal ocean of elevated nutrients and contaminants leading to eutrophication, algal overgrowth, and coral disease. Freshwater discharging directly from submarine groundwater vents off of Kahekili Beach Park, Kaanapali, in West Maui contains elevated nutrient concentrations and lower pH values. Coral cores were collected in July 2013 from the shallow reef at Kahekili in Kaanapali, West Maui, Hawaii from scleractinian Porites lobata to specifically addresses the relationship between coral reef health and compounding stressors from contaminated submarine groundwater discharge.
Time-series of seawater carbonate chemistry variables, including salinity, dissolved inorganic nutrients, pH, total alkalinity, and dissolved inorganic carbon from sites along Kahekili Beach Park, west Maui near submarine groundwater seeps and living coral reefs. Samples for seawater were collected by pumping bottom water from the seafloor using a peristaltic pump and collecting discrete water samples every 4-hrs over a 6-day period.
