Oceanography is inherently an interdisciplinary science capable of producing highly complex, heterogeneous data that pose unique challenges for data management and reuse. Evolving instrumentation and new research methodologies are increasingly taxing current strategies and technologies for management and reuse of data. Data-related publisher and funder requirements are relatively new demands that researchers must learn to navigate. These are just some of the stressors that repositories experience in their role of curating and publishing FAIR marine-related data. In response, oceanographic repositories are adapting by leveraging community data standards, engaging in the development of new technologies and the usage of novel tools to improve data discovery and interoperability. Additionally, they are collaborating with data-related stakeholders to help shape data-related policy, and fill an education role to promote good data hygiene and bring awareness of concepts like FAIR to the oceanographic research community. This presentation will highlight some of the activities of the BCO-DMO repository that are aimed at advancing the availability and reuse of Open oceanographic data. 

Spatial and temporal trends of remotely sensed sea-ice cover, sea surface temperatures, chlorophyll-a concentration and primary production in the Baffin Bay, Davis Strait and Labrador Sea were analyzed for the 1998–2017 period. We found spatial variability in the trends of these cryospheric, biologic and oceanographic phenomena. For example, in the northern Baffin Bay, we observed decreases in annual sea-ice persistence, yet increases along the Labrador Sea-ice edge during winter, with the latter having significant correlations with broader atmospheric patterns. In general, we observed increases in summer sea surface temperatures across the study region, except a small area of cooling along the southern Greenlandic coast. We also found significant negative trends in April chlorophyll-a and primary production followed by significant positive trends for both biological phenomena in May, owing to anomalously high values in 2014 and 2015. Notably, we found a significant positive correlation between days of monthly sea ice presence in April with May primary production quantities. Finally, we found a significant positive trend in total annual primary production over the study period. This novel finding suggests an important relationship between the timing of breakup along the sea-ice edge and peaks in biological production.
