Light attenuation characteristics of glacially-fed lakes [PDF]

open access: yes, 2014
Transparency is a fundamental characteristic of aquatic ecosystems and is highly responsive to changes in climate and land use. The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic of these changes.

Palynology, vegetation and climate of the Waikato lowlands, North Island, New Zealand, since c. 18,000 years ago [PDF]

open access: yes, 1989
The vegetational and climatic history of the Waikato lowlands during the last c. 18,000 years is inferred from the palynology of sediment cores from Lakes Rotomanuka, Rotokauri, and Okoroire.

Identification of Hazard and Risk for Glacial Lakes in the Nepal Himalaya Using Satellite Imagery from 2000–2015 [PDF]

open access: yes, 2017
Glacial lakes in the Nepal Himalaya can threaten downstream communities and have large socio-economic consequences if an outburst flood occurs. This study identified 131 glacial lakes in Nepal in 2015 that are greater than 0.1 km ²and performed a first ...

Calcite covering of sediment as a possible way of curbing blue-green algae [PDF]

open access: yes, 1992
Natural calcite precipitation in lakes is a well-known control mechanism of eutrophication. In hard-water lakes, calcite deposits on the flat bottoms of shallow lakes and near the shores of deeper lakes resulted from biogenic decalcification during the ...

Progress in palynology of the Gelasian–Calabrian Stages in Europe: Ten messages [PDF]

open access: yes, 2007
Europe has at present the most extensive network of palynological sites covering the Late Pliocene and the Early Pleistocene or roughly the Gelasian-Calabrian Stages. This paper covers ten points of recent progress in the palynology of this time period:
