The lakes sampled include two near the coast (AT1 and AT4) and two at the head of the fjord (SS1381 and SS8). Paleoenvironmental proxies measured include Loss-on-Ignition (LOI), Mass Accumulation Rate (MAR), bulk density, plus Calcium and Titanium content derived from XRF. Kangerlussuaq lake locations: SS1381: 67.014°N, 51.102°W, 196m elevation, 18m water depth. SS8: 67.011°N, 51.074°W, 188m elevation, 10m water depth. AT1: 66.968°N, 53.402°W, 475m elevation, 16m water depth. AT4: 66.965°N, 53.499°W, 200m elevation, 17m water depth. ABSTRACT SUPPLIED BY ORIGINATOR: The Kangerlussuaq area of southwest Greenland is a lake-rich landscape that covers a climate gradient: a more maritime, cooler and wetter coastal zone contrasts with a dry, continental interior. Radiocarbon- dated sediment sequences (covering ~11,200-8,300 cal year) from paired lakes at the coast and the head of the fjord were analysed for lithostratigraphic variables (organic-matter content, bulk density, Ti, Ca). Minerogenic and carbon accumulation rates from the four lakes were compared to determine catchment and lake response to Holocene climatic variability. Catchment erosion at the coast was dominated by cryonival processes, with considerable sediment production due to the limited vegetation cover and exposed rock faces. Input of minerogenic sediment at one site (AT4) was high (>1 gDW cm-2 year-1) during the period 5,800-4,000 cal year BP, perhaps reflecting intensification of cryogenic processes on northeast-facing slopes and rapid delivery to the lake. This period of erosional activity was not observed at the nearby, higher elevation site (AT1) due to the lower catchment relief; instead, there was an abrupt decline in carbon and minerogenic accumulation rates at ~5,800 cal year BP. Sediment accumulation rates at the inland sites were much lower (<0.005 gDW cm-2 year-1) reflecting greater catchment stability (more extensive vegetation cover), lower relief and substantially lower precipitation, but synchronous increases in mineral accumulation rates from ~1,200 to 1,000 cal year BP may reflect wind erosion associated with regional cooling and local aridity. Carbon-accumulation-rate profiles were similar at the two inland sites, with higher-than-average accumulation (~6-8 g C m-2 year-1) during the early Holocene and a subsequent decline after ~6,000 cal year BP. At the inland lakes, both mineral and carbon accumulation rates exhibited a stronger link to climate, driven by trends in effective precipitation and regional aeolian activity. Catchment differences (relief, altitude) lead to more individualistic records in both erosion history and lake productivity at the coast.
