Heat-Driven Shifts in NC Waters Elevate Health Risks

Warmer North Carolina waters—driven by climate change—are expanding the season for harmful algae and microbes, with rare but deadly infections from Naegleria fowleri and Vibrio vulnificus highlighting evolving waterborne risks; while most recreational sites meet safety standards, experts warn that warmer, shallow, slow-moving waters can foster blooms and bacteria, urging avoidance of bright green or discolored water and keeping warm freshwater out of the nose.

NASA's New TROPOMI Tool Revolutionizes Algal Bloom Tracking

NASA's TROPOMI instrument, designed to measure air pollution, has demonstrated its ability to detect harmful algal blooms by capturing the faint red glow emitted by the algae responsible for these blooms. TROPOMI's advanced imaging capabilities allow it to penetrate thin cloud cover and gather twice as much fluorescence information as previous methods relying on ocean color. This technology could help federal agencies and local communities better forecast and manage harmful outbreaks, protecting public health and coastal ecosystems. Additionally, upcoming satellite missions like NASA's PACE will further enhance our ability to monitor algal blooms and other factors affecting marine ecosystems.

Toxic Algae Bloom Kills Hundreds of Sea Lions and Dolphins on Southern California Coast

Marine mammal rescue organizations have reported hundreds of sick and dead sea lions and dolphins along the Southern California coast this month, with experts blaming a bloom of harmful algae. The algae produces domoic acid, a neurotoxin that enters the food chain and sickens marine mammals as they eat prey. Tissue samples have been collected for tests to confirm the animals are victims of domoic acid, which is also a risk to people who eat crustaceans, fish, and shellfish that have accumulated elevated levels. The current outbreak is unusually severe, with high concentrations of domoic acid found from Orange County north to San Luis Obispo County, but especially in the Santa Barbara Channel off Santa Barbara and Ventura counties.
