Measuring the contaminated sediment transport processes in a strongly stratified urban estuary
Presentation at PECS 2012 Talk, (The Physics of Estuaries and Coastal Seas Symposium, 12-16 August 2012)
Title: Salt-Wedge dynamics and effects on contaminated sediment transport in the Duwamish River estuary, Seattle, WA
Lydia Kapsenberg is a graduate student at University of California, Santa Barbara. Lydia deployed several SBE 37-SMP-ODO MicroCATs and SeaFET pH sensors off the California coast to quantify the biological and physical sources of pH variability. Lydia presented a poster on her work at the 2014 Ocean Science Meeting.
Danielle Claar is a Ph.D. candidate working jointly with University of Victoria (Canada) and the University of Hawaii (USA) on Kiritimati (Christmas) Island in the Central Pacific. Her research focuses on the drivers of coral reef resilience in the context of increasing anthropogenic stress. In her research, she conducts field surveys and integrates large-scale spatial datasets to disentangle environmental and human drivers in reef ecosystems. Currently, she is investigating the interaction between environmental stressors (increased water temperature and decreased water quality) and diversity of coral symbionts (Symbiodinium). Her ultimate goal is to inform coral reef management at a global scale.
Danielle is shown here installing an SBE 37-SMP-ODO MicroCAT (moored CTD with optical oxygen sensor) alongside a WET Labs ECO fluorometer on the coral reef of Christmas Island in February 2015. She also is installing multiple temperature sensors (SBE 56 Temperature Logger) to temporally map the reef’s temperature spatial variations.

Molly Burdick-Whipp is an M.S. candidate working with California State University, Long Beach. Her project is in a highly developed urban lagoon (Colorado Lagoon) that is currently undergoing restoration. Restoration begain in 2009, and has included redirecting storm water runoff and removing 63,000 cubic yards of contaminated sediment. The next restoration phase, expected to begin in three to 5 years, will include removal of the culvert and creation of an open water channel connecting the lagoon to the adjacent Alamitos Bay to restore tidal influence in the lagoon. The culvert is currently the only connection between the lagoon and bay, and the new channel should improve circulation and hence water quality conditions for the lagoon. Molly will conduct long-term water quality observations in both systems in 2015 using an SBE 37-SMP-ODO MicroCAT (moored CTD with optical oxygen sensor) and an ECO FLNTU in each bay. While instruments are moored, she will simultaneously monitor the fish movement between the bay and lagoon during the various seasons using acoustic telemetry techniques. Her goal is to quantify the degre of movement of estuarine fish predators between the bay and lagoon, and document the physical environment and food supply to provide mechanistic explanations for these movement patterns. Her work will also provide high quality and resolution baseline observations prior to the open water channel restoration effort.
Arley Muth is a Ph.D. candidate at the University of Texas at Austin. She will be using two SBE 37-SM MicroCAT CT(D) Recorders and two WET Labs ECO FLNTUs, along with Satlantic SeaFET pH sensors, to study the salinity and pH regimes of the nearshore Beaufort Sea in relation to the epilithic communities of the Boulder Patch kelp community.
Michael Acquafredda is a Ph.D. candidate at Rutgers University. He will be using two WET Labs ECO FLNTUs and one WET Labs Water Quality Monitor at shallow, subtidal aquaculture sites along the New Jersey shoreline to study the effect of food availability (i.e., chlorophyll), turbidity, salinity, and temperature on the growth, health, and survival of surf clams.
