“…There was a similar drop in localised SST records around New Zealand (Barrows et al, 2007a); Figure 8E) that is also reflected in speleothem records indicating cooler conditions at 67-63 ka and wetter conditions at 71-61 ka (Williams et al, 2015). An even greater SST reduction occurred off the west coast of northern Patagonia, where temperatures reached their lowest levels of the last glacial cycle (Kaiser et al, 2005; Figure 8F).…”

“…In this interval, dust and IRD records show little change beyond occasional small peaks Caniupán et al, 2011;Figure 8K and L) and SSTs were equivalent to those during the Holocene (Barrows et al, 2007a). Antarctic temperatures warmed following MIS 4 (EPICA, 2006), and early MIS 3 showed a strong millennial-scale pattern of warming and cooling into and out of the A4-1 events (Blunier & Brook, 2001; Figure 8D).…”

“…Secondly, the forcing factors behind southern mid-latitude glaciation during the last glacial cycle are ambiguous, as is the relationship to climatic drivers in the Northern Hemisphere. For example, insolation does not appear to directly control Southern Hemisphere climate change (Huybers & Denton, 2008;Doughty et al, 2015), whereas the movement of the southern westerly winds and oceanic frontal systems have been invoked as drivers of climate and glacial advances by controlling precipitation and sea surface temperatures (Lamy et al, 2004(Lamy et al, , 2007Barrows et al, 2007a;Denton et al, 2010). The roles of sea ice and ocean stratification, whilst likely important, also remain unclear (Allen et al, 2011;Denton et al, 2010;Putnam et al, 2013b).…”

Glaciers respond to climate variations and leave geomorphic evidence that represents an important terrestrial paleoclimate record. However, the accuracy of paleoclimate reconstructions from glacial geology is limited by the challenge of representing mountain meteorology in numerical models. Precipitation is usually treated in a simple manner and yet represents difficult-to-characterize variables such as amount, distribution, and phase. Furthermore, precipitation distributions during a glacial probably differed from present-day interglacial patterns. We applied two models to investigate glacier sensitivity to temperature and precipitation in the eastern Southern Alps of New Zealand. A 2-D model was used to quantify variations in the length of the reconstructed glaciers resulting from plausible precipitation distributions compared to variations in length resulting from change in mean annual air temperature and precipitation amount. A 1-D model was used to quantify variations in length resulting from interannual climate variability. Assuming that present-day interglacial values represent precipitation distributions during the last glacial, a range of plausible present-day precipitation distributions resulted in uncertainty in the Last Glacial Maximum length of the Pukaki Glacier of 17.1 km (24%) and the Rakaia Glacier of 9.3 km (25%), corresponding to a 0.5°C difference in temperature. Smaller changes in glacier length resulted from a 50% decrease in precipitation amount from present-day values (À14% and À18%) and from a 50% increase in precipitation amount (5% and 9%). Our results demonstrate that precipitation distribution can produce considerable variation in simulated glacier extents and that reconstructions of paleoglaciers should include this uncertainty.

Changes in the position of the Subtropical Front south of New Zealand since the last glacial period

This study fills an important gap in our understanding of past changes in the Southern Subtropical Front (S-STF) in the southwest Pacific Ocean. Paleo-sea surface temperatures (SST) were estimated from planktic foraminiferal census counts from cores straddling the modern S-STF in the Solander Trough, south of New Zealand. The estimated SST were compared for 6 time slices; glacial period (25-21 ka), Last Glacial Maximum (LGM; 21-18 ka), early deglaciation (18-16 ka), late deglacial/early Holocene period (14-8 ka), mid-Holocene period (8-4 ka), and late Holocene period (4-0 ka). The position of the S-STF was determined by two methods:(1) the location of the 10°C isotherm and (2) the location of the highest SST gradients. These new results suggest that the S-STF was not continuous between east and west of New Zealand during the glacial period. Steep SST gradients indicate that a strong S-STF rapidly shifted south during the LGM and early deglaciation. During the late deglacial and Holocene periods the position of the S-STF differs between the two methods with reduced SST gradients, suggesting a more diffuse S-STF in the Solander Trough at this time. The glacial SST data suggest that the S-STF shifted north to the west of New Zealand, while to the east there was a stronger SST gradient across the front. This was possibly the result of an increased wind stress curl, which could have been caused by stronger, or more northerly Southern Hemisphere westerly winds (SHWW), or a merging of the SHWW split jet in this region.
