Ocean acidification has been linked to the disturbance of food webs and changing species distributions. Together with other biogeochemical changes, increasing ocean acidification may compromise the health of marine ecosystems as well as negatively impact many ocean goods and services and the communities that rely on them.
Sea level rise is a global problem. This blog post highlights a key paradox about sea level rise: since it occurs relatively slowly, it can be easy to think it’s not happening. But, if you’re not seeing it, you’re just not looking in the right place.
CanVis is a simple software program that allows users to visualize potential impacts of coastal development or climate change (inundation, SLR) allowing conservation planners and stakeholders to better understand the impacts of their decisions.
Key changes to ocean systems include acidification, rising sea levels, and strengthening storms. Impacts to ocean habitats are detailed in the discussion of coral bleaching and reef degradation in the species and habitats section.
The Coastal Flood Exposure Mapper supports users undertaking a community-based approach to assessing coastal hazard risks and vulnerabilities by providing maps that show people, places, and natural resources exposed to coastal flooding. This spatial visualization tool shows maps of people, places, and natural resources exposed to coastal flood hazards including FEMA flood zones, shallow coastal flooding, sea level rise, storm surge.
NOAA’s Coastal Inundation Mapping Primer offers a four-step process for inundation mapping that includes: obtaining and preparing elevation data, preparing water level information, mapping inundation, and visualizing inundation.
NOAA’s Coastal Inundation Toolkit assists users with planning for inundation. The Toolkit is designed to help communities determine their coastal flooding vulnerability and what steps they can take to reduce this risk and can be a valuable resource for incorporating climate change impacts into conservation planning.
LIDAR —Light Detection and Ranging — is a remote sensing method used to examine the surface of the Earth. Coastal Lidar reflects elevation information, which is a primary data consideration for management activities in the coastal zone, including conservation.
The warmer air and ocean surface temperatures brought on by climate change impact corals and alter coral reef communities by prompting coral bleaching events and altering ocean chemistry. These impacts affect corals and the many organisms that use coral reefs as habitat. Reef degradation also reduces the ability of these systems to respond to change and mitigate storm surge events – a valuable ecosystem service.
This online, self-guided resource shows spatial analysts how to incorporate green infrastructure into their GIS work to prioritize areas that will help reduce hazard and climate impacts.
