• U-series measurements performed upon a Scottish soil chronosequence
•The soils have experienced both U addition and leaching, to varying
degrees
•Weathering rates are similar to other high-latitude boreal catchments
•High-latitude rivers comprise an important U flux with high
(234U/238U) to the ocean

key words: sea level change, shoreline, coastal, beach, erosion,
recession, Hawaii
•We examine relations between shoreline change and sea-level rise (SLR)
in Hawaii.
•SLR rates are significantly different between Oahu and Maui Islands
(95% C.I.).
•Maui beaches, with SLR 65% greater than Oahu, are significantly most
erosional.
•We examine human, oceanographic, and geomorphologic influences on
shoreline trends.
•Differing SLR remains as the best explanation for differing shoreline
trends.

3.Environmental variability in the monsoon-westerlies
transition zone during the last 1200 years: lake sediment analyses from central
Mongolia and supra-regional synthesis

・high resolution
multi-proxy (pollen, grain size, total organic carbon) record from a small
mountain lake (Lake Khuisiin; 46.6°N, 101.8°E, 2270 m a.s.l) in central
Mongolia has been used to explore changes in vegetation and climate over the
last 1200 years.
・Environmental
changes were generally subtle and climate change seems to have been the major
driver of variations in vegetation until at least the early part of the 20th
century, suggesting that either the level of human activity was generally low,
or the relationship between human activity and vegetation did not alter
substantially between AD 760 and 1839.
・Both the
reconstructions and the moisture levels simulation on a millennium scale
performed in the MPI Earth System Model indicate that the monsoon-westerlies
transition area shoes a greater climate variability than those areas influenced
by the westerlies, or by the summer monsoon only.
4. Glaciation style and the geomorphological
record: evidence for Younger Dryas glaciers in the eastern Lake District,
northwest England

•Detailed mapping was undertaken in the eastern Lake
District, NW England.
•The last glaciation in the area was more extensive and
complex than previously thought.
•Summit icefields and outlet glaciers were widespread.
•Variations in valley-floor landform development reflect
changing glaciation styles.
•Using moraine morphology as a relative dating technique
can be unreliable.

• First well replicated, centennial, multi-parameter TRW,
δ13C/δ18O record from teak.
•δ13C and δ18O records reveal significant higher rainfall
signals than tree-ring widths.
•Tree-ring δ18O responds to peak dry and rainy season
rainfall.
•High-resolution δ18OTR values can distinguish seasonal
rainfall variability.
•Reconstruction of seasonal rainfall variability over
Indonesia is possible with δ18OTR.

•We evaluate a pollen-climate transfer function at the
tundra-taiga transition.
•Mean July temperature and annual precipitation can be
inferred.
•A Holocene reconstruction from the Siberian Arctic was
evaluated.
•We discuss the power and limits of our transfer
function.
