Late Holocene Climate-Flood Relationships on the Lower Ohio River
… the Lower Ohio River and their relationship with climate are investigated using a ca. 2000-year-long sediment core collected from Goose Pond, Indiana. Using high-resolution radiocarbon dating (n = 25), late Holocene sedimentation rates were calculated for Goose Pond. Changes in sediment …

Palaeoenvironmental reconstruction of late Holocene climate dynamics in Southwest Africa using a multi-proxy characterization of Namaqualand mudbelt sediments
… the recognized importance of understanding late Holocene climatic changes in southern Africa, a dearth of available evidence has resulted in a frag- mented view of the recent past. South Africa has been identified as a key focus region for palaeoclimatic studies, as it reflects the dynamics …

Testing the late-Holocene climate signal from ombrotrophic bogs in southernmost Chile and the Falkland Islands: a multi-proxy, multi-profile and multi-site approach
… (SWW), offer the potential of reliable palaeoclimate archives. This investigation aimed to test the late-Holocene climate signal related to variability of the SWW. Three sites were investigated: San Juan and Karukinka bog, southernmost Chile and San Carlos, a Sphagnum dominated bog, discovered …

Chironomid-based paleotemperature reconstruction of the North Slave Region, Northwest Territories during the Late Holocene
I reconstructed late Holocene mean July air temperatures using a chironomid-based inference model based on lake sediment collected from two shallow lakes within the North Slave Region, Northwest Territories. No significant shifts were identified in the chironomid species assemblages, which …

A 1400 Year Multi-Proxy Record of Hydrologic Variability in the Gulf Of Mexico: Exploring Ocean-Continent Linkages During the Late Holocene
Late Holocene climate variability includes the Little Ice Age (LIA, 450-150 BP) and the Medieval Warm Period (MWP, 1100-700 BP) that are characterized by contrasting hydrologic and thermal regimes. The degree of interaction between the North American continent and the ocean during these two abrupt …

Biogeomorphology and soil geomorphology of small semiarid basins, northeastern Arizona : influences of topoclimate and climate variations
In northeastern Arizona, on the Colorado Plateau, landscapes associated with weakly cemented sandstones are sensitive to Holocene climate changes on millennial to decadal scales. It is hypothesized that these climate changes affect processes of weathering, erosion and plant community establishment …

Late quaternary palaeoenvironments of the Sandveld, Western Cape Province, South Africa
… prompts a fresh synthesis as to the nature of late Quaternary environmental changes in the southwestern Cape's fynbos biome. The study is centred on Verlorenvlei, a remote coastal lake and swamp system which is ideally situated to investigate the complex interactions between late Holocene …

Climatic signals and frequencies in the Swedish Time Scale, River Ångermanälven, Central Sweden
Any future climate variation forced by human activities will be superimposed on the background of natural climate variation. Therefore, before interpreting the present climate and addressing future climate scenarios some knowledge of past climate is necessary. This thesis offers a rare glimpse into …
