GLODAPv2: North Pacific Ocean CTD and Bottle Profiles, 2000

North Pacific Ocean and Sea of Okhotsk data from the 2000 PROFESSOR KHROMOV cruise includes hydrographic and chemical profiles. Measurements likely contain dissolved oxygen, nitrate, nitrite, phosphate, silicate, salinity, water temperature, and potential temperature. The dataset is part of the GLODAPv2 compilation, collected using CTD and bottle instruments.

Use Cases

• Analyzing ocean carbon cycle dynamics based on dissolved oxygen and nutrient measurements.
• Studying water mass formation and circulation using salinity and potential temperature profiles.
• Calibrating biogeochemical models with discrete sample data for nitrate and phosphate.
• Investigating seasonal or interannual variability in the Sea of Okhotsk using the 2000 time-stamped observations.

Strengths

• Contains a specific suite of nine measured variables, including dissolved oxygen and multiple nutrients.
• Data is part of the authoritative GLODAPv2 (Global Ocean Data Analysis Project) compilation.
• Covers a defined geographic region (North Pacific Ocean and Sea of Okhotsk) over a specific 34-day cruise in 2000.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• Conflicting 'last updated' dates exist between platforms (2000-07-05 vs. 2026-03-05), creating provenance uncertainty.
• Row count, file size, and license information are uniformly absent from all source descriptions.
