2018 Shelfwide Cruise – Completed
The bottom area of low oxygen in Louisiana coastal waters west of the Mississippi River, commonly known as the ‘Dead Zone,’ was mapped at a smaller-than-average size this summer. The area was 2,720 square miles (7,040 square kilometers), slightly larger than the state of Delaware and well below the projected estimate of 6,570 square miles (17,000 square kilometers).

Cruise Dedication
The 2018 shelf-wide cruise to determine the extent of low oxygen bottom waters on the Louisiana-Texas continental shelf is dedicated to the memory of Dr. Wesley J. Tunnell, Jr. who passed away on Saturday, July 14, 2018, after a long successful and not successful battle with cancer.
What is hypoxia?
Hypoxia, or low oxygen, is an environmental phenomenon where the concentration of dissolved oxygen in the water column decreases to a level that can no longer support living aquatic organisms. Hypoxic areas, or “Dead Zones,” have increased in duration and frequency across our planet’s oceans since first being noted in the 1970s.
The largest hypoxic zone currently affecting the United States, and the second largest hypoxic zone worldwide, is the northern Gulf of Mexico adjacent to the Mississippi River.
