Abstract:
Abstract. A new annually resolved sedimentary record of Southern
Hemisphere mid-latitude hydroclimate was recovered from Lake Ohau, South
Island, New Zealand, in March 2016. The Lake Ohau Climate History (LOCH)
project acquired cores from two sites (LOCH-1 and -2) that preserve sequences
of laminated mud that accumulated since the lake formed ∼ 17 000 years
ago. Cores were recovered using a purpose-built barge and drilling system
designed to recover soft sediment from thick sedimentary sequences in lake
systems up to 150 m deep. This system can be transported in two to three
40 ft long shipping containers and is suitable for use in a range of
geographic locations. A comprehensive suite of data has been collected from
the sedimentary sequence using state-of-the-art analytical equipment and
techniques. These new observations of past environmental variability augment
the historical instrumental record and are currently being integrated with
regional climate and hydrological modelling studies to explore causes of
variability in extreme/flood events over the past several millennia.
