Methods and datasets:

Our group uses three different methods to collect data on hypoxia. These include 1) long-term deployment of instruments on stationary moorings, 2) monthly cruises of fixed offshore transects, and 3) an annual shelfwide cruise to map the widest extent of hypoxia during each summer.

  • Monthly C+F Transects
  • Annual Mid-Summer Shelfwide Cruise (1985-Present)

    Research Overview

    Since 1985, routine and consistent field data collection in the northern Gulf of Mexico has allowed us to:

    • Document the temporal and spatial extent of hypoxia
    • Identify the hydrographic, chemical, and biological variables related to the development and maintenance of hypoxia
    • Develop predictive models of the relationship between riverine nutrient loading and the size and severity of the hypoxic zone

    These long-term physical and biological observations provide a synthetic, interdisciplinary dataset that directly supports greater scientific understanding, improved predictive modeling, and policy development related to nutrient management within the Mississippi River Basin and natural resource management within the Gulf of Mexico.
