Assemblage Composition of Large Benthic Foraminifera in the Coastal Waters of Likupang, Northeastern Sulawesi, Indonesia
Description
This dataset documents the diversity (species and genera) and assemblage composition of large benthic foraminifera collected from coastal waters of Likupang in northeastern Sulawesi, Indonesia, during July-August 2024. Sampling was conducted across three distinct coastal habitats: a tourism area (TA), a mangrove area (MA), and a village area (VA) (see Figure 1 and Table 1 for site details). The full dataset is provided in Tables 2-19.

Steps to reproduce
Within each sampling area, three stations were established. At each station, samples were collected from every distinct microhabitat or substratum type using a selective sampling protocol. SCUBA divers collected approximately 50 g (wet weight) of material from the top 1–3 cm of surface sediment, rubble, or algal turf. We targeted the total assemblage (including both living and dead tests). In the laboratory, samples were washed with freshwater through a 63-µm mesh sieve to remove fine fractions and were subsequently sun-dried. The dried residues were carefully sorted to isolate intact foraminiferal tests. Specimens were identified to the lowest possible taxonomic level (typically genus or species) using a light microscope equipped with a digital camera. Taxonomic identification was achieved by comparing imaged specimens against authenticated reference specimens and consulting photographic entries in the World Register of Marine Species (WoRMS) (https://www.marinespecies.org/index.php) and the World Foraminifera Database (https://www.marinespecies.org/foraminifera/).
