European Ocean Biodiversity Information System

This dataset contains coccolithophore abundance data from surface underway samples collected during the JC039 cruise in the Atlantic between Falmouth, UK and Punta Arenas, Chile in October to December 2009. Samples were collected from the non-toxic water supply 3 times per day, approximately every 3 to 4 hours spaced between CTD stations. Coccolith and cell counts were collected on Millipore HA (nitrocellulose) filters which were rinsed with a potassium tetraborate buffer and frozen at 20 degrees C. Samples were then dried and mounted onto slides using Norland Optical Adhesive. These were then enumerated by birefringence microscopy. These data were collected by scientists from the Bigelow Laboratory for Ocean Sciences and contribute to the Atlantic Meridional Transect (AMT) project.
