Site 1053 is located at the top of an escarpment cut into the upper part of Blake Nose (29°59.5385'N, 76°31.4135'W). The total core recovery was 189.5 m of upper middle to upper Eocene deposits. An exceptionally thick upper Eocene section was recovered, consisting mainly of siliceous nannofossil ooze (Norris, Kroon, Klaus, et al., 1998, doi:10.2973/odp.proc.ir.171B.1998). These Eocene sediments are unconsolidated as they were not buried by younger deposits. This chapter discusses the distribution of organic walled dinoflagellate cysts (dinocysts) at Hole 1053A. Bio(chrono)stratigraphic divisions cited here follow the initial assignment by the Leg 171B Shipboard Scientific Party (Norris, Kroon, Klaus, et al., 1998, doi:10.2973/odp.proc.ir.171B.1998).

Sediment depth is given in mbsf. #1 = species is present in the sample but not included in the total count.
