Physical and geochemical data from shelf sediments eastern Antarctica

Shelf sediment samples were collected in Eastern Antarctica with the mega corer in 2023 (April). The sample locations and water depths are recorded in this dataset. These samples were used to collect data on organic matter (total organic carbon, total nitrogen, delta 13C (organic), delta 15N, and C to N ratios). Nutrient data (nitrate, nitrite, sulfate, and ammonia) and grain size analysis were collected on a subsample set.
