9. Diatom
response to climate forcing of a deep, alpine lake (Lugu Hu, Yunnan, SW China)
during the Last Glacial Maximum and its implications for understanding regional
monsoon variability
Qian Wang, Xiangdong
Yang, N. John Anderson, Enlou Zhang, Yanling Li
Volume 86, 15 February
2014, Pages 1–12
•A
high-resolution diatom record from a deep alpine lake of SW China is presented.
•Response
of diatom is synchronous with North Hemisphere summer solar radiation.
•The mean
winter temperatures at least ∼6 °C lower than present occur during
LGM.
•Abrupt
events (such as YD) are not captured in the diatom and pollen records.
•We confirm
sensitivity of sub-tropical Alpine lake to climate and catchment process.
10. A
deglacial and Holocene record of climate variability in south-central Alaska
from stable oxygen isotopes and plant macrofossils in peat
Miriam C. Jones, Matthew
Wooller, Dorothy M. Peteet
•We analyzed macrofossils and oxygen isotopes in a Lateglacial peat core
in Alaska.
•Oxygen isotopes vary with temperature and strength of the Aleutian Low.
•Patterns are broadly consistent across the region.
•Higher peat carbon accumulation corresponds to greater summer vs. winter
moisture.

lacustrine record, northwestern Yunnan Province, southwestern China
Xiayun Xiao, Simon G.
Haberle, Ji Shen, Xiangdong Yang, Yong Han, Enlou Zhang, Sumin Wang
•We reconstruct a regional vegetation succession framework based on pollen
data.
•Early- to mid-Holocene: a gradual transition from cold–dry climate to
warm–humid one.
•The Holocene climatic optimum occurred at ∼6100 cal. yr BP in our study area.
•Sea-level change and SST may be more important regional forcing
mechanisms.

4–2) cold part.
•Changes in degree of continentality characterized climate variability
during MIS 5–2.

into pollen source area, transport and deposition from modern pollen
accumulation rates in lake sediments
Isabelle Matthias, Thomas Giesecke
•Pollen accumulation rates (PAR) from lake sediment and biomass are linear
related.
•Nearby vegetation determines PAR for small lakes.
•The trunk-space component needs to be considered in the dispersal models.
•Dispersal models capture aspects of the absolute pollen vegetation
relationship.
•Regional difference in net primary production may be reflected by PAR.

•The Eemian
sea-level highstand persisted from ca 130 until 124 ka BP in the
eastern Baltic.
•The Baltic
Sea–White Sea connection persisted for ca 6 kyr.
•Water temperature estimates reveal a strong thermal stratification in the
eastern Baltic.
•This reveals the mixing of waters from the White Sea and the North Sea in
the area.
•Submerged area in the Russian Karelia could have assisted the development
of an oceanic climate in Europe.

Salomon, F. Albarède
•New data shed light on the connection between the Trajan basin and the
Tiber river.
•Three control factors are identified: salinity, oxygenation, and
anthropogenic activity.
•A fluvial origin is suggested for clay and silt and higher salinity
exposure for sand.
•Isolation of the Trajan harbor may have been triggered by an alluvial
plug.
•Geochemistry adequately restore paleoenvironmental conditions in ancient
harbors.
