Benthic foraminiferal faunas and benthic stable isotopes during the last 20kyr were investigated in core MD02-2488 (46°28.8′S, 88°01.3′E, 3420m water depth) from the southeast Indian Ocean sector of the Southern Ocean in order to document paleoceanographic changes from the last glacial, through deglaciation and into the Holocene. Variations occurred in the accumulation rates, species composition, diversity, and stable isotopes during the last 20kyr. The benthic δ 18 O and δ 13 C records during the last ~28kyr show that no significant deep water circulation changes took place before ~15.6calendar kyr (ka). The δ 13 C increase at 15.6ka is interpreted as reflecting the arrival of better ventilated deep waters at the site and is associated with the progressive increase in % of miliolids from ~15ka to 0ka, an interval (~16–15ka) of low benthic foraminiferal accumulation rates (BFARs) and an increase in the relative abundance of Stainforthia complanata. Deep waters were ~2.2±0.4°C colder during the last glacial than at present. Carbonate dissolution proxies indicate that carbonate dissolution was higher during the last glacial than during the last deglacial and Holocene. BFARs and the percentage of species indicative of high-productivity suggest that the flux of organic matter resulting from surface water productivity was generally higher between ~20 and 13ka than between ~12 and 0ka, consistent with the observed higher proportion of biosiliceous sediment at ~20–14ka and published records. The combined percentages of the two most abundant species, Alabaminella weddellensis and Epistominella exigua (‘phytodetritus species’), suggest that seasonality of productivity (intermittency of primary productivity) fluctuated over the last 20kyr and was higher during the last glacial and deglaciation (20–10ka) compared with the Holocene (10–0ka). The relative abundances of A. weddellensis and E. exigua do not covary over the last 20kyr, an observation also reported from other areas.
