Replanting the Bay's Underwater Meadows

In June, Dr. Kathy Boyer, associate professor of biology at San Francisco State University’s Romberg Tiburon Center, began a nine-year effort to restore 70 acres of native eelgrass in the SF Bay. The work is funded by settlement money from the Cosco Busan oil spill that emptied 58,000 gallons into the San Francisco Bay in 2007. Bay Nature. August 26, 2014


Planting meadows in the ocean: technique may help restore disappearing seagrass beds

Seagrass meadows form important parts of many ocean ecosystems, but are disappearing due to human impacts. A study published recently in PLoS ONE found that they could benefit from a restoration technique using seed-filled pearl nets. August 11, 2014


Variation at multiple trophic levels mediates a novel seagrass-grazer interaction

Seagrass ecology research conducted by RTC alumna Lindsey Carr and Dr. Kathy Boyer reveals complex interactions with grazers and predators.  Marine Ecology Progress Series 508: 117-128.  August 4, 2014


Native Eelgrass Transplant and Seeding

Why are these buoys in the water? RTC and NOAA explain SF Bay eelgrass restoration funded by the 2007 Cosco Busan oil spill damage assessment. (pdf, 736kb) August 4, 2014


Retail Operations Close at Drakes Bay Oyster Company

RTC's Dr. Katharyn Boyer and Joe Mueller of COM recommend a thorough study and an inventory of Drakes Estero’s natural resources after the oyster farm shuts down. July 31, 2014


Drought impacts phytoplankton blooms in northern San Francisco Bay and Delta

Major – but rare – spring blooms in 2014 in San Francisco Bay Delta, California, a result of the long-term drought, increased residence time, and altered nutrient loads and forms. Journal of Experimental Marine Biology & Ecology. July 14, 2014


Dr. Ellen Hines conducts research on rare marine mammals in Southeast Asia

Two recent papers share findings on coastal Irrawaddy dolphins in Thailand and dugongs in Malaysia. Both species are listed as Vulnerable on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. In some locations, Irrawaddy dolphins are listed as critically endangered. Dr Hines' research addresses population and community ecology of threatened and endangered species as related to local conservation efforts. July 7, 2014


Dr. Kathy Boyer's Wetlands Ecology Lab keeps busy with multiple eelgrass research projects

While the Living Shorelines Project is in the monitoring phase, the Wetlands Ecology Lab is keeping busy with two new projects. In late June, they spent several 16-hour days harvesting and replanting the first 4 of 36 acres of eelgrass in Central SF Bay for Pacific herring habitat. The nine-year, $2.5 million project was funded from the 2007 Cosco Busan oil spill Damage Assessment and Restoration Plan, completed in February 2012. With a few days rest, they are now monitoring eelgrass plots as part of the Zostera Experimental Network led by the Smithsonian Institute's J. Emmett Duffy. June 25, 2014


Phytoplankton, Considered the World’s Lungs, Are in Deep Trouble From Climate Change

A new study funded by the National Science Foundation has found that the world’s phytoplankton may be in serious jeopardy due to climate change. Listen to the radio segment with Dr. Bill Cochlan or read about the research. June 18, 2014


Ocean acidification cruise explored effects pH on marine food web

A collaborative team of scientists led by RTC's Dr. William Cochlan measured nutritional quality and toxicity of phytoplankton in corrosive waters. Two Teachers-at-Sea from Texas and Tennessee also joined the expedition. June 11, 2014


RTC Scientists Participate in 2nd Google Science Fair Hangout

Associate Professor Kathy Boyer hosted a Google Hangout On Air for Google Science Fair 2014 and Connected Classrooms on Friday, June 13 at 10am, on the topic of restoring coastal ecosystems. Watch the recorded Hangout here. June 10, 2014
