Coastal Alaska Nutrient Profiles from 1998-1999 Bottle Casts

Concentration profiles of seven nitrogen species, including total nitrogen, nitrate, ammonia, and urea, were collected from bottle casts in Alaskan coastal waters. The dataset was submitted by the University of Alaska Fairbanks Institute of Marine Science for the GLOBEC project. Measurements span from March 1998 to December 1999 aboard the research vessel ALPHA HELIX.

Use Cases

• Modeling dissolved organic nitrogen distribution against other nitrogen species.
• Analyzing seasonal or spatial trends in nitrate and ammonia concentrations.
• Correlating total organic nitrogen levels with other environmental parameters from the GLOBEC project.
• Studying the urea cycle in subarctic coastal waters using the urea concentration data.

Strengths

• Profiles for seven distinct nitrogen species provide a detailed chemical view.
• Data collection spans a 21-month period, capturing seasonal variation.
