Modeling hydrography and marine sedimentation in the Cariaco Basin since the Last Glacial Maximum [PDF]

, 2009
The Cariaco Basin has shallow connections with the Caribbean Sea, and these are further reduced at times of lower sea level, such as at the Last Glacial Maximum (LGM).

A tephrostratigraphic investigation of the continuously varved Holocene Boreal lake Nautajärvi, Finland, provides precise age estimate for Lairg A/Hekla 5 eruption

Journal of Quaternary Science, EarlyView.
ABSTRACT Numerous cryptotephra layers originating from Icelandic volcanoes and further afield have reached Northern Europe during the Holocene. Refining the precise timing and the relative frequency of local and distal eruptions requires well‐resolved continuous sediment archives. Lake Nautajärvi is located in central‐southern Finland (61°48′ N, 24°41′

Remote Observation of a Small Meteotsunami in the Bight of Benin Using HF Radar Operating in Lower HF Band

IEEE Access, 2019
High-frequency (HF) surface-wave (SW) radar systems have demonstrated their capability to capture the signals from seismic and non-seismic tsunami events using the estimation of surface current changes. Several ocean radar systems, operating in the upper

Mountainous vegetation succession and land use during the last millennium in the Peloponnese (southern Greece): Environmental change and economic development in an isolated periphery

Journal of Quaternary Science, EarlyView.
ABSTRACT Mediterranean mountainous areas and their valuable natural resources have long been attractive to human societies. The Peloponnese (southern Greece), with its complex topographic and climatic variability, has been the scenery for the development of numerous human communities.

Numerical solutions of a boundary value problem on the sphere using radial basis functions [PDF]

, 2016
Boundary value problems on the unit sphere arise naturally in geophysics and oceanography when scientists model a physical quantity on large scales. Robust numerical methods play an important role in solving these problems.

Nutrient enrichment—but not warming—increases nitrous oxide emissions from shallow lake mesocosms

Limnology and Oceanography, EarlyView.
Abstract Shallow lakes and ponds play a crucial role in the processing of carbon and other nutrients. However, many lakes and ponds worldwide are affected by climate change and nutrient pollution. How these pressures affect the emission of the greenhouse gas nitrous oxide (N2O) is unclear.
