This cruise is an ongoing collaborative project with sampling taking place on a monthly basis whenever possible. Future data will be made available as soon as it is processed. Casts 178-252 were added March 2026 with the same processing steps followed. High Dissolved Oxygen values were seen at some stations in Neroustos Inlet. Turbidity was removed from casts 1 to 104 due to the sensor needing calibration. The Fluorometer did not always have enough range, actual values may exceed those seen in the data for events 1-3, 126, 154 and 155.
