Researchers Identify Sources of Nitrogen in Macroalgae in Hawaiʻi
Macroalgae (algae visible to the naked eye) is sometimes called “seaweed” and holds a place in ocean health. It is generally beneficial and serves to regulate nutrient levels, including nitrogen. Excessive human-caused or natural input of nutrients such as nitrogen can cause undesirable algal blooms and outbreaks.
NOAA-sponsored researchers published the first comprehensive survey of nitrogen sources in macroalgae from shallow to mesophotic depths (0–385 feet deep) in the Hawaiian Archipelago. They compared samples from shallow and mesophotic depths in the Monument as well as the Main Hawaiian Islands.
