Postspreading Rifting in the Adare Basin, Antarctica: Regional Tectonic Consequences

Kinematic solutions for this time interval suggest a southward decrease in relative motion between East and West Antarctica. Here we present multichannel seismic reflection and seafloor mapping data acquired within and near the Adare Basin on a recent geophysical cruise. We have traced the ANTOSTRAT seismic stratigraphic framework from the northwest Ross Sea into the Adare Basin, verified and tied to DSDP drill sites 273 and 274. Our results reveal three distinct periods of tectonic activity. An early localized deforma- tional event took place close to the cessation of seafloor spreading in the Adare Basin (∼24 Ma).

Ice Shelf Advance and Retreat Rates Along the Coast of Queen Maud Land, Antarctica K
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 106, NO. C4, PAGES 7097–7106, APRIL 15, 2001 Ice shelf advance and retreat rates along the coast of Queen Maud Land, Antarctica K. T. Kim,1 K. C. Jezek,2 and H. G. Sohn3 Byrd Polar Research Center, The Ohio State University, Columbus, Ohio Abstract. We mapped ice shelf margins along the Queen Maud Land coast, Antarctica, in a study of ice shelf margin variability over time. Our objective was to determine the behavior of ice shelves at similar latitudes but different longitudes relative to ice shelves that are dramatically retreating along the Antarctic Peninsula, possibly in response to changing global climate. We measured coastline positions from 1963 satellite reconnaissance photography and 1997 RADARSAT synthetic aperture radar image data for comparison with coastlines inferred by other researchers who used Landsat data from the mid-1970s. We show that these ice shelves lost ϳ6.8% of their total area between 1963 and 1997. Most of the areal reduction occurred between 1963 and the mid-1970s. Since then, ice margin positions have stabilized or even readvanced. We conclude that these ice shelves are in a near-equilibrium state with the coastal environment. 1.

Mount Harding, Grove Mountains, East Antarctica
MEASURE 2 - ANNEX Management Plan for Antarctic Specially Protected Area No 168 MOUNT HARDING, GROVE MOUNTAINS, EAST ANTARCTICA 1. Introduction The Grove Mountains (72o20’-73o10’S, 73o50’-75o40’E) are located approximately 400km inland (south) of the Larsemann Hills in Princess Elizabeth Land, East Antarctica, on the eastern bank of the Lambert Rift(Map A). Mount Harding (72°512 -72°572 S, 74°532 -75°122 E) is the largest mount around Grove Mountains region, and located in the core area of the Grove Mountains that presents a ridge-valley physiognomies consisting of nunataks, trending NNE-SSW and is 200m above the surface of blue ice (Map B). The primary reason for designation of the Area as an Antarctic Specially Protected Area is to protect the unique geomorphological features of the area for scientific research on the evolutionary history of East Antarctic Ice Sheet (EAIS), while widening the category in the Antarctic protected areas system. Research on the evolutionary history of EAIS plays an important role in reconstructing the past climatic evolution in global scale. Up to now, a key constraint on the understanding of the EAIS behaviour remains the lack of direct evidence of ice sheet surface levels for constraining ice sheet models during known glacial maxima and minima in the post-14 Ma period. The remains of the fluctuation of ice sheet surface preserved around Mount Harding, will most probably provide the precious direct evidences for reconstructing the EAIS behaviour. There are glacial erosion and wind-erosion physiognomies which are rare in nature and extremely vulnerable, such as the ice-core pyramid, the ventifact, etc.

Here we present palynological results from an Oligocene to Miocene sediment record provided by the Integrated Ocean Drilling Program Expedition 318 to the Wilkes Land margin (East Antarctica). The Oligocene assemblages (33.9-23 Ma) are dominated by pollen and spores from temperate forest and sub-Antarctic shrub vegetation inhabiting different altitudinal zones. These in- clude a lowland cold temperate forest with Dacrydium and Lagarostrobos (both common in southern forests of New Zealand and Tasmania today) and a high altitude tundra shrubland comprising Microcachrys, Nothofagus (southern beech) and Podocarpaceae conifers.

Bracegirdle, Gareth J.

This 12 warming has contributed to the regional retreat of glaciers2, disintegration of floating 13 ice shelves3 and a ‘greening’ through the expansion in range of various flora4. Several 14 interlinked processes have been suggested as contributing to the warming, including 15 stratospheric ozone depletion5, local sea ice loss6, an increase in the westerly winds5, 7, 16 and changes in the strength and location of low-high latitude atmospheric 17 teleconnections8, 9. Here we use a stacked temperature record to show an absence of 18 regional warming since the late 1990s. The annual mean temperature has decreased at a 19 statistically significant rate, with the most rapid cooling during the Austral summer. 20 Temperatures have decreased as a consequence of a greater frequency of cold, east to 21 south-easterly winds resulting from more cyclonic conditions in the northern Weddell 22 Sea associated with a strengthening mid-latitude jet. These circulation changes have 23 also increased the advection of sea ice towards the east coast of the peninsula, 24 amplifying their effects.

Very few studies have been exploring the influence of climate anomalies on the AIS and only a vague estimate of its impact is available. Changes to the ice sheet are quantified using observations from space-borne altimetry and gravimetry missions. We use data from Envisat (2002 to 2010) and Gravity Recovery And Climate Experiment (GRACE) (2002 to 2016) missions to estimate monthly elevation changes and mass changes, respectively. Similar estimates of the changes are made using weather variables (surface mass balance (SMB) and temperature) from a regional climate model (RACMO2.3p2) as inputs to a firn compaction (FC) model. Elevation changes estimated from different techniques are in good agreement with each other across the AIS especially in West Antarctica, Antarctic Peninsula, and along the coasts of East Antarctica. Inter-annual height change patterns are then extracted using for the first time an empirical mode decomposition followed by a principal component analysis to Citation: Kaitheri, A.; Mémin, A.; investigate for influences of climate anomalies on the AIS.

Dipwells were inserted to monitor changes in depth to, and volume of, groundwater and tracer tests were conducted to estimate aquifer hydraulic conductivity and groundwater velocity. During summer (November–February), meltwater forms a shallow, unconfined, aquifer perched on impermeable ice cemented soil. Groundwater extent and volume depends on the amount of snowfall as meltwater is primarily sourced from melting snow drifts. Groundwater velocity through the permeable gravel and sand was up to 7.8 m day-1, and hydraulic conductivities of 4.7 × 10-4 m s-1 to 3.7 × 10-5 m s-1 were measured. The presence of the penguin rookery, and the proximity of the sea, affects groundwater chemistry with elevated concentrations of salts (1205 mg L-1 sodium, 332 mg L-1 potassium) and nutrients (193 mg L-1 nitrate, 833 mg L-1 ammonia, 10 mg L-1 total phosphorus) compared with groundwater sourced away from the rookery, and with other terrestrial waters in Antarctica.
