Study launched to document fate of algal toxin in sediment

in Eutrophication, Harmful Algal Blooms Comments are Disabled

SCCWRP and its partners have initiated a study examining whether an algal toxin known as domoic acid can linger in seafloor sediment following a harmful algal bloom (HAB) event. The … More

An expert panel of 10 leading global experts on pteropods convenes at SCCWRP in
September to reach consensus on biologically relevant thresholds for tracking the
impacts of ocean acidification on coastal marine health. The experts, pictured with
SCCWRP staff who facilitated the panel’s deliberations, traveled from as far away
as Great Britain, Italy and British Columbia.

International expert panel convened to develop acidification thresholds for pteropods

A 10-member panel made up of leading global experts on pteropods, or sea snails, convened at SCCWRP in September to develop consensus around biologically relevant thresholds at which these ubiquitous … More

SCCWRP’s Dario Diehl prepares to fly a multispectral imaging sensor mounted to an unmanned aerial system (UAS), bottom left, over Lake Elsinore in Riverside County. In the background, researchers in a boat collect surface water samples. SCCWRP and its partners are working to adapt UAS technology to cost-effectively monitor lakes for evidence of harmful algal blooms.

SCCWRP and its partners have launched an effort to adapt commercially available unmanned aerial systems (UAS) for routine monitoring of lakes susceptible to ecologically disruptive cyanobacteria blooms. UAS technology – … More

SCCWRP’s Dr. Nabiul Afrooz prepares to evaluate the ability of bioretention soil media to remove contaminants from stormwater runoff. The lab setup is designed to mimic much larger stormwater biofiltration units that are constructed in areas such as parking lots.

Bioretention soil media being tested to compare effectiveness at treating stormwater

in Runoff Water Quality, Stormwater BMPs Comments are Disabled

SCCWRP and its partners in October launched a year-long project to test the performance of six types of bioretention soil media designed to remove pathogens, indicator bacteria, nutrients, metals and … More

A metal cage containing passive sampling arrays is retrieved off the coast of Santa Rosa Island in the Channel Islands National Marine Sanctuary in August following a two-month deployment. The passive samplers help measure the chemical concentration of persistent organic pollutants (POPs) at the site; the findings will feed into an international study documenting background concentrations of POPs in coastal ocean water around the world.

Passive samplers retrieved from Channel Islands for international oceanic pollutants study

in Emerging Contaminants Comments are Disabled

SCCWRP and its partners in August successfully retrieved two sets of passive sampling arrays that were deployed over a two-month period near the Channel Islands to help establish baseline concentrations … More

SCCWRP’s Syd Kotar monitors water quality inside a mobile exposure unit on the banks of the Los Angeles River just downstream of the L.A.-Glendale Water Reclamation Plant. The units house fish that are exposed to flowing river water in real time, enabling researchers to evaluate the fish afterward for potential biological impacts from exposure to chemical contaminants in the water.

Fish exposed to flowing river water to monitor for biological changes

in Bioanalytical Cell Screening Assays, Emerging Contaminants Comments are Disabled

SCCWRP and its partners exposed fish to flowing Los Angeles River water for two weeks in September as part of a pilot study examining potential biological impacts from exposure to … More

in Climate Change, Ocean Acidification and Hypoxia Comments are Disabled

West Coast researchers working to develop a computer model that predicts how the region’s coastal waters will be affected by ocean acidification and hypoxia have advanced to a second phase … More

Field data collection completed for Santa Margarita River nutrient management study

in Eutrophication, Harmful Algal Blooms Comments are Disabled

SCCWRP and its partners have completed field data collection for a three-year project seeking to establish scientifically defensible nutrient loading targets for reducing eutrophication and improving biological integrity in the … More

Representatives from the Utah Department of Agriculture and Food receive training in a SCCWRP laboratory on how to deploy a passive sampling technology to monitor for harmful algal blooms (HABs) in irrigation systems in Utah. The pilot project is part of a coordinated, multi-agency effort to develop robust HABs monitoring methods for more types of aquatic environments.
