Climate Change

Organic and Total Alkalinity, San Francisco Estuary, California Collected and titrated water samples from multiple habitats in the north San Francisco Bay estuary for measures of total and organic alkalinity. The organic contributors to total alkalinity are commonly assumed negligible in total alkalinity measures. Recent research reveals organic alkalinity is noticeable in estuaries, and when assumed absent, affects estuarine carbonate chemistry calculations when total alkalinity is used. By titrating for organic alkalinity, this research provided more comprehensive insight on spatial and temporal estuarine alkalinity and carbonate chemistry trends. This insight is needed for more accurate assessments of climate change, such as acidification, in estuaries.

Ecological Restoration

Sediment Investigation, California Worked with teams to evaluate and restore Zostera marina (eelgrass) sites in various areas throughout the San Francisco Bay estuary. Assessments included sampling for zooplankton and megafauna at restoration sites to determine levels of species diversity and richness before and after site restoration.
