Oceanic uptake of anthropogenic carbon dioxide (CO2) from the atmosphere has changed ocean biogeochemistry and threatened the health of organisms through a process known as ocean acidification (OA). Such large-scale changes affect ecosystem functions and can have effects on societal uses, fisheries resources, and economies. In many large estuaries, anthropogenic CO2-induced acidification is enhanced by strong stratification, long water residence times, eutrophication, and a weak acid–base buffer capacity. In this article, we review how a variety of processes influence aquatic acid–base properties in estuarine waters, including river–ocean mixing, upwelling, air–water gas exchange, biological production and subsequent respiration, anaerobic respiration, calcium carbonate (CaCO3) dissolution, and benthic inputs…

AOML Scientists Assess Hurricane Delta’s Rapid Intensification

NOAA aircraft reconnaissance continued for Major Hurricane Delta on October 6, capturing the system’s quick maturation overnight. P-3 and G-IV missions are scheduled every 12 and 24 hours from Lakeland, FL. The National Hurricane Center (NHC) tasked NOAA’s Hurricane Hunters to identify the location and strength of the circulation center, and to survey the atmospheric conditions nearby and ahead of Delta. Instrumentation onboard the aircraft have sampled the system’s development, revealing a 55 knot rapid intensification in just 24 hours.

AOML Scientists use Hurricane Hunter Data to Analyze Gaps in Hurricane Rain Coverage

A new study published in Remote Sensing uses radar data from NOAA’s P-3 Hurricane Hunter aircraft to determine the characteristics a satellite would need to measure the surface wind in a tropical cyclone between areas of heavy rainfall. This study finds that satellites with higher resolution can measure larger regions of heavy rainfall.
