Abstract : The aim of this study was to determine the abundance of phytoplankton in the thermocline layer of Sangihe Talaud Islands. The research was conducted in 33 stations in October 2018 and the samples were taken at the thermocline depth using a rosette sampler as much as 10 L Environmental parameter, namely temperature, salinity, and depth, was measured using the SBE 911-Plus CTD (Conductivity Temperature Depth). The water samples were concentrated into 40 mL using plankton net with mesh size 20 µm. The phytoplankton enumeration was conducted using the Sedgwick-Rafter Cell Counter under a 100x magnification microscope and identified to the species level. Mapping of the phytoplankton abundance, temperature, and salinity in form of contours was conducted by Surfer 9 software, and the similarities among stations were analyzed based on the Bray-Curtis index using Biodiversity Pro Ver.2 software. The result showed there were 84 species found during sampling with an abundance of 7059-542,222 cell m-3. The highest abundance was observed to be as a result of warm water temperatures, while low abundance were observed in some stations due to the presence of high salinity level. Based on the Bray-Curtis index, 2 pairs of stations had a similarity >50%. This was associated with the general similarities found in the community.
