Seagrass Restoration Project
University of California, Santa Cruz
Without seagrass, we would lose a fifth of our fisheries.1 Eelgrass is a species of seagrass that along with coastal kelp are threatened by human activity and climate change. Scientists estimate that kelp and seagrasses2:

• capture 83 million metric tons of carbon per year;
• one square meter of seagrass can generate 10 liters of oxygen each day; and
• one acre of healthy seagrass can sustain 40,000 fish and tens of millions of small invertebrates
• counter ocean acidification and nitrification.

We supported a high impact remediation effort for eelgrass restoration that achieved the following:

• Restored eelgrass populations to pre-disturbance conditions of the 1930s. Grew 16 fold.
• Measured the effect of eelgrass beds on biodiversity, adding to the growing body of research.
• Enhanced knowledge on increasing the success rates of eelgrass remediation. Eelgrass restoration is more successful with the presence of sea otters, and when it is planted in the right conditions, with light availability and current flow.
• Final results here and handbook here.

Moro Cojo Nutrient Monitoring Project
Central Coast Wetlands Group

The Central Coast Wetlands Group (CCWG) is an affiliate research group at Moss Landing Marine Laboratories (MLML) focused on the study, preservation, and restoration of Central Coast Wetlands. Dr. Kim Null, a water quality researcher at MLML, has been working with CCWG constructing models of nutrient sources to Moro Cojo Slough, a subwatershed of Elkhorn Slough. Dr. Null identified hotspots where nutrients enter the estuary and proposed that these sites should be constantly monitored to establish a nitrogen load baseline, validate models, and verify nutrient reductions due to mitigation efforts.

With funding from Anthrocean the CCWG has built a continuous monitoring platform that monitors nitrate, dissolved oxygen, temperature, salinity, chlorophyll, and pH in real time. Before the Anthrocean funding, data was gathered through grab samples, providing only a snapshot of nutrient concentrations at a specific point in time. Now, the data is continuously collected providing a high resolution of water quality parameters and nitrate loads. The data and platform designs are open to the public and workshops will be held in the near future. With this high resolution dataset, future remediation efforts such as bioreactors and wetland installations, will be detectable with a high degree of certainty.

Native Oyster Restoration
Elkhorn Slough National Estuarine Research Reserve
Anthrocean also supported aquaculture and restoration of native Olympia oysters in the Elkhorn Slough by Prof. Kerstin Wasson, since they had failed to reproduce. The final report can be found here.
