Coasts

Climate experts estimate that by 2100, sea level could rise by up to 70 inches and that the frequency, intensity and flood-effects of storms could increase. People in coastal areas should understand how sea level rise (SLR) may affect their homes, schools, roads, public facilities, natural resources and habitat areas, and how to prepare for these impacts.

This updated addition to the Post-Disaster Redevelopment Planning: A Guide for Florida Communities guidebook, referred to in this document as the Addendum, represents the fifth phase of the Statewide Post-Disaster Redevelopment Planning Initiative. The initial four phases provided vulnerable communities a planning process to guide post-disaster redevelopment activities that enhance community sustainability and ensure resilient redevelopment after any disaster.

Propagule supply is fundamental in regulating the strength of demographic and genetic interactions in natural populations. In marine systems, recent studies focusing on benthic fish and invertebrate species with long planktonic durations have found that propagule production and supply are de-coupled by physical transport processes. Most benthic marine populations therefore have been considered demographically open, whereby recruitment is driven by remote propagule production. Few studies have focused on species with shorter planktonic durations (e. g., seaweeds).

Ecosystem-based management of coastal marine resources is based, in part, on scientific understanding of the broad (i.e. ecosystem-wide) consequences of human uses of the coastal environment, including resource extraction and degradation of habitats. To wisely manage these resources, a clear understanding of the potential impacts of human activities on the resource and the ecosystem is essential.

Upwelling in the California Current System (CCS) sustains a productive ecosystem and is mediated by alongshore, equatorward wind stress. A decades‐old hypothesis proposes that global warming will accelerate these upwelling favorable winds. Recent analyses provide empirical support for upwelling intensification in the poleward portion of the CCS. However, these studies rely on proxies for upwelling and are limited in their ability to distinguish anthropogenic forcing from internal climate variability.

Climate experts estimate that by 2100, sea level could rise by around 70 inches and that the frequency, intensity and flood-effects of storms will increase. People in coastal areas need to understand how sea level rise may affect their homes, schools, roads, public facilities, natural resources and habitat areas, and how to prepare for them. Collaboration: Sea-level Marin Adaptation Response Team (C-SMART) is working to develop this understanding for Marin’s ocean coast, so that together, we can prepare to meet the challenge of sea level rise.

This research has shown that kelp forest restoration is possible in barrens when purple urchins are selectively removed. These results provide support for the large-scale habitat restoration that is now being performed along the Palos Verdes Peninsula in cooperation with other local non-profits and commercial fishermen.

This Article aims to distill the lessons of Washington’s experience with ocean acidification (OA) policy and apply them to the political framework that exists in California.
