Marshes on the Margins

Sarah Giddingsnews

21 March 2018 – Harvey and Giddings participated in a workshop that was part of the Marshes on the Margins project. Marshes on the Margins is investigating how heavily altered Southern California estuaries will be impacted by sea level rise, particularly thinking towards restoration strategies. The workshop was focused on Los Peñasquitos Lagoon as a case study location. Harvey presented the data she has collected and work she has done towards understanding the system as part of her dissertation.

San Diego Bay Field Work Underway

As one of five major ports in California, San Diego Bay is an important hub for industry and commerce, as well as the  U.S. Navy Pacific Fleet.  The bay consists of nearly 11,000 acres of marine habitat for a diverse aquatic population that helps sustain various fauna that use the bay for breeding, rearing young, and migratory respite.  Among the many organisms that call the bay home are sea turtles and the California Least Tern.  As anthropogenic activities alter the landscape, environmental stresses put on these organisms have changed their migration and foraging patterns.

A collaborative project between SIO and SPAWAR SSC-Pacific is currently underway to improve upon the current understanding of the mechanisms driving San Diego Bay environmental conditions and circulation patterns to asses their role in ecological function of the bay.    By assessing its modern hydrographic state, quantifying flow fields, and contextualizing the physical data with existing biological data, we hope to gain a better understanding of the system as a whole, which will ultimately allow for better stewardship of the resources that the bay provides.

 A key focus of this project is shoal-channel interaction during the time period when the south bay becomes consistently saltier than the ocean (i.e. summertime in San Diego).  This is intended to be a topic in Angelica’s dissertation and her summer internship with SPAWAR through the NREIP.

Major Los Peñasquitos field experiment complete!

As part of her dissertation work, Maddie led a large field experiment in Los Peñasquitos Lagoon that just recently wrapped up. In addition to her typical deployments (pressure sensors, current meters, salinity/temperature sensors, etc.) she also deployed a Distributed Temperature Sensor (DTS) which consists of a long cable that can effectively measure temperature at very high spatial resolution. This month-long deployment required going to the lagoon multiple times per week to collect data and check on equipment.

Heitor presents at the 2017 UCSD URC

Heitor presented his research in our group at the 2017 UCSD Undergraduate Research Conference and got excellent feedback! Very excited to have him working with us and expanding upon an interactive model visualization tool which we hope to release by this coming summer!!

Heitor presenting at one of our past group meetings x infinity! He had to connect to another computer via video conference in order to present so it resulted in an infinite string of images of himself!

 

 

Angelica and Maddie are PhD Candidates!!!

Sarah Giddingsnews

Congratulations to Angelica Rodriguez and Maddie Harvey for passing their qualifying exams! Angelica advanced to candidacy on 21 March 2017 and Maddie advanced to candidacy on 6 December 2017. I am super proud of my students, they are all doing an excellent job! Here they are engulfing Angelica in a hug after her post-quals celebratory lunch!
