Vertical And Cross-Shore Distributions Of Barnacle Larvae In La Jolla, Ca Nearshore Waters: Implications For Larval Transport Processes, Malloree Lynn Hagerty

Theses

Many marine organisms begin their lives as tiny larvae that are at the mercy of ocean currents. Understanding the transport and subsequent dispersal of larvae is crucial, as it drives population connectivity in the ocean. Larval transport is a complex process involving both physical motions of the water and larval behavior. Vertical positioning is especially important because currents vary throughout the water column, and larvae at different depths will be advected differently. With swimming speeds insufficient to swim against currents, marine larvae can mediate cross-shore transport by controlling their depth distributions. Thus, the overall objective of this study was to …

Legal Risk Analysis For Sea Level Rise Adaption Strategies In San Diego, San Diego Regional Climate Collaborative, Environmental Law Institute

San Diego Regional Climate Collaborative

This Executive Summary, put together by the Environmental Law Institute for the San Diego Regional Climate Collaborative, breaks down the findings of a full report, which concisely summarizes the legal risks and administrative hurdles associated with different adaptation strategies in order to facilitate informed decision-making. The information provided in this document is not legal advice, but designed to be a primer on multiple types of legal risk and administrative hurdles associated with sea level rise adaptation for Southern California municipalities.

Challenges And Opportunities For Climate-Smart Stormwater Management In San Diego, Laura Walsh

San Diego Regional Climate Collaborative

The purpose of this Gap Analysis is to identify challenges and opportunities for agencies in San Diego to better manage stormwater with climate-smart strategies. In this report, ‘climate-smart’ refers to a stormwater tactic that increases a system’s resiliency to both extreme dry and wet season flows while also enhancing local communities, businesses, and/or natural resources.

Comparing Sea Level Rise Adaptation Strategies In San Diego: An Application Of The Noaa Economic Framework, Nexus Planning & Research

San Diego Regional Climate Collaborative

Coastal communities in San Diego County face ever-increasing risks from sea level rise, coastal storm events, flooding, and beach erosion. The potential hazards to this vital, vibrant 70-mile stretch of California coastline compel city planners and decision-makers to develop coastal resilience initiatives by conducting vulnerability assessments and considering potential adaptation strategies.

Nexus Planning & Research was tasked with providing a comparative benefit-cost analysis of coastal resilience strategies for participating cities in San Diego County, following the framework outlined in the National Oceanic and Atmospheric Administration’s (NOAA) funded study, What Will Adaptation Cost? An Economic Framework for Coastal Community Infrastructure (NOAA, …

The Effect Of Watershed Runoff And Sediment Resuspension On Turbidity And Sediment Deposition In St. John, Us Virgin Islands: Implications For Watershed And Marine Development And Restoration In Bays With Coral Reefs, Stephen E. Campbell

Theses

In the US Virgin Islands (USVI), land-based (terrigenous) sedimentation has been identified as a major cause of coral stress. Development, such as the building of unpaved roads in steep coastal watersheds, has increased sediment yields and marine terrigenous sedimentation by up to an order of magnitude above background levels. When activated during storm events, ephemeral streams transport sediment from the watershed to coastal waters. Once deposited on the seafloor, resuspension of benthic sediments can further increase turbidity and deposition. However, isolating the relative contributions of runoff and resuspension to turbidity and deposition using conventional sediment trap monitoring has been challenging. …

Larval Rockfish Diversity Abundance Dynamics In Association With A Marine Protected Area In The Southern California Bight, Dustin Chen

Theses

Marine protected areas (MPAs) are areas aimed at protecting natural and cultural resources that are often proposed as a way to alleviate the effects of overfishing on populations of targeted species; these areas have varying degrees of fishing and recreational use restrictions. In order to assess MPA efficacy, it is important to determine the mechanisms by which the presence of MPAs affect reproductive output within and potentially even beyond their boundaries. I attempted to address this through studying the responses of rockfish (Sebastes spp.) larval abundances to the presence of the Cowcod Conservation Areas (CCAs) located within the Southern California …

2016 San Diego Regional Climate Collaborative Annual Report, San Diego Regional Climate Collaborative

San Diego Regional Climate Collaborative

The San Diego Regional Climate Collaborative is a network for public agencies that serves the San Diego region to share expertise, leverage resources and advance comprehensive solutions to facilitate climate change planning. By partnering with academia, nonprofits, and businesses, the SDRCC also works to leverage the profile of regional leadership. This is the 2016 San Diego Regional Climate Collaborative Annual Report.
