Maritimes Region Historical Ocean Tracking Network (OTN) Project Moored Time Series Data

They were designed in collaboration with Satlantic, and can be deployed to a depth of 330m. The objective of these pods was to monitor and report key oceanographic parameters to provide environmental context to animal movements and validation data to sophisticated biogeochemical and physical ocean models. The sensors mounted include: - Satlantic STOR-X data/power manager - Digiquartz Paroscientific pressure sensor - VEMCO VR4 acoustic receiver - Sea-Bird 37SIP Microcat ( seabird.com/moored/sbe-37-si-and-sip-microcat/family?productCategoryId=54627473785 ) - Aanderaa dissolved oxygen sensor (3830 & 4330; aanderaa.com/productsdetail.php?Oxygen-Optodes-2 ) - Satlantic 15V, 102Ah alkaline battery pack The STOR-X controls the sampling of the oceanographic instrumentation.

The sensors sample for 30s every hour on the hour. Data stored on the receivers or benthic pods can be recovered via acoustic modem from either vessels or autonomous vehicles such as gliders. Some of the data from the benthic pods were processed by the Bedford Institute of Oceanography (BIO).
