For this study 853 water-bottle samples were collected from 150 sites during seven surveys carried out from November 2005 to July 2010. Samples were ﬁxed in acidiﬁed Lugol’s iodine solution and cell concentrations were counted with an inverted light microscope. Results revealed the presence of 65 species of which Achradina pulchra, Asterodinium gracile, Brachydinium capitatum, Ceratoperidinium yeye, Craspedotella pileolus, Dicroerisma psilonereiella, Erythropsidinium agile, Karenia asteriochroma, K. bicuneiformis, Pronoctiluca rostrata, Scaphodinium mirabile, Warnowia juno, W. maxima and W. rosea were new records for the southern Gulf of Mexico. Most of these species are illustrated. Gyrodinium fusiforme and Karenia brevis were the most abundant species with the highest records of 44.9 million and 5.4 million cells/L, respectively. Species distribution is brieﬂy discussed in relation to published literature.

Biological and Geological Perspectives of Dinoflagellates
This volume provides an overview of current research on fossil and modern dinoflagellates, as well as highlighting research areas for future collaboration, following the DINO9 International Conference in Liverpool. The volume is organized into four themes, with a review paper for each theme written by the key-note speaker. Each theme also includes a future research foci note following discussion during the conference. The contributions are organized into the following sections: environmental change, ecology/palaeoecology, life cycles and diversity, and stratigraphy and evolution. Also included are notes from two workshops: culture experiments and dinocysts as palaeoceanographic tracers. This volume will be of interest to both the biological and Micropalaeontological communities.
