Powerful winds aren't the only deadly force during tropical storms. The greatest threat to life is storm surge.
On August 3, the National Geodetic Survey (NGS) began collecting aerial damage assessment images of areas affected by Tropical Storm Isaias. Imagery is being collected in specific areas identified by NOAA in coordination with the U.S. Coast Guard. Collected images are available to view online via the NGS aerial imagery viewer.
Beach dunes, mangroves, wetlands, rain gardens, and bioswales are just a few examples of what experts call natural and nature-based infrastructure. In our latest podcast, Kim Penn from NOAA’s Office for Coastal Management talks about how simple nature-based systems not only minimize coastal flooding, erosion, and runoff — but also form wonderful areas for recreation and tourism.
NOAA's Precision Marine Navigation team is creating new online services to enable more efficient access to the NOAA data that powers private-sector marine navigation products. The goal is to foster innovation, improve navigation safety, aid in more efficient coastal route planning, and help mariners make informed decisions as they navigate our nation's waterways.
The Lake Erie HAB Forecast now incorporates a 3D hydrodynamic model to better understand what's going on beneath the surface of Lake Erie, critical to managing drinking water intakes and prime fishing spots. In addition, the forecast website is easier to use, with animations and dashboards to help users better understand maps and key elements.
In August 2019, researchers diving in Papahānaumokuākea Marine National Monument expected to see brilliant pinks and greens, characteristic of native stony corals. Instead, they saw mats of a red alga they did not recognize, stretching for the length of football fields and smothering the native corals.
In our latest post, I’ve asked William Sweet, an oceanographer from our Center for Operational Oceanographic Products and Services (CO-OPS), to share highlights from the 2019 State of U.S. High Tide Flooding with a 2020 Outlook, and what NOS is doing to address a nationwide problem commonly known as “high tide flooding.”
