Atlantic Meridional Transect cruise JC039 Coccolithophore composition - light microscopy (CTD bottles)

This dataset contains coccolithophore abundance data from CTD bottle samples collected during the JC039 cruise in the Atlantic between Falmouth, UK and Punta Arenas, Chile in October-December 2009. Niskin samples were collected during the pre-dawn CTD (second cast of the day) from six light depths (1%, 7%, 14%, 33%, 55%, 97%) and from two deeper (down to 200 m) depths for coccolith enumeration. Coccolith and cell counts were collected on Millipore HA (nitrocellulose) filters which were rinsed with a potassium tetraborate buffer and frozen at 20 degC. Samples were then dried and mounted onto slides using Norland Optical Adhesive. These were then enumerated by birefringence microscopy (Balch et al. 2011). These data were collected by scientists from the Bigelow Laboratory for Ocean Sciences and contribute to the Atlantic Meridional Transect (AMT) project.
