Seawater radioisotope (234Th) and carbon from sampling conducted at the Compass Station in Bedford Basin, Nova Scotia, Canada from April to August 2019

These data include seawater radioisotope (234Th) and carbon data collected at the Compass Station in Bedford Basin, Nova Scotia, Canada at three time periods from April to August 2019. Niskins (2L to 10L) were used to obtain the water samples. Four liters of water were used for total 234Th and ~42 L were used to filter size-fractionated particulate 234Th and carbon. Two in-line filters were used: >51 µm and ~ 1 µm. Filters were analyzed via non-destructive beta counting (234Th) and then for carbon content. These data were collected in conjunction with sediment coring samples that were measured for 234Th and carbon content to assess carbon export and the carbon budget of Bedford Basin.
