The Next Decade of Seismic Oceanography: Possibilities, Challenges and Solutions

Frontiers in Marine Science, 2022
Seismic reflection profiling of thermohaline structure has the potential to transform our understanding of oceanic mixing and circulation. This profiling, which is known as seismic oceanography, yields acoustic images that extend from the sea surface to ...

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Waiting for the rains: An attempt to evaluate the efficiency of the large Roman cistern at Barbariga Stancija (Casematte, Istria, Croatia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Access to freshwater has always been a critical factor in sustaining human settlements, especially in regions with limited water resources. In the Mediterranean region, where dry summers and karst landscapes limit water availability, ancient societies developed advanced methods for collecting and storing rainwater. Among these, cisterns played

The local paleoenvironment of Kalavan‐2 based on small‐vertebrate remains and its implications for human‐environment‐dynamics between 60 and 35 ka in the Armenian Highlands

Journal of Quaternary Science, EarlyView.
ABSTRACT Kalavan‐2, a high‐altitude (∼1640 m a.s.l.) open‐air site in Armenia, preserves stratified Middle Paleolithic occupations with a rich small‐vertebrate record. Luminescence dating has placed site formation between ~60 and 45 ka, but without independent chronological control of the microvertebrate accumulation.

Intensification of the Southern Hemisphere westerly winds during the last deglaciation (18.5–14.0 cal ka BP): Evidence from Pearly Beach wetland on the southern Cape coast of South Africa

Journal of Quaternary Science, EarlyView.
ABSTRACT The southwestern Cape of South Africa experiences a complex and dynamic climate, shaped by the interplay between the temperate Southern Hemisphere westerly winds and the subtropical easterlies. Despite the climatic sensitivity of the region, relatively few studies have examined how conditions have varied since the last deglaciation in response

Atlas of Shipwrecks in Inner Ionian Sea (Greece): A Remote Sensing Approach

Heritage, 2020
Underwater cultural heritage (UCH) sites constitute an important part of the overall cultural heritage both nationally and globally as they carry cultural, environmental, scientific, technological, political, economic and social viewpoints.

Holocene climate oscillations, seismotectonic events and human–environmental interactions reconstructed from the Giannades palaeolake on Corfu (Eastern Mediterranean, Greece)

Journal of Quaternary Science, EarlyView.
ABSTRACT The Mediterranean is particularly sensitive to rapid climate changes (RCCs) during the Holocene. An increasing number of natural climate archives revealed that socio‐economic developments were influenced by such RCCs since the Palaeolithic. However, multi‐millennial and high‐resolution archives are still rare and often located in mountainous ...

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Use of the Acoustic Doppler Current Profiler (ADCP) in the study of the circulation of the Adriatic Sea [PDF]

Annales Geophysicae, 2001
The results of basin-wide vessel-mounted ADCP measurements carried out from May 1995 through February 1996 in the Adriatic Sea are analysed in order to characterise the tidal flow, the steady current field and some specific sub-basin scale features.

Combining multibeam and single beam echosounders for quantifying gas bubble release from the seafloor

Limnology and Oceanography: Methods, EarlyView.
Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...
