Thermokarst Lagoons: Distribution, Classification and Dynamics in Permafrost‐to‐Marine Transitions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The transition of permafrost landscapes to marine environments, driven by climate change, plays a crucial role in the global carbon cycle. Thermokarst lagoons, formed along permafrost coasts when thermokarst lakes get connected to the sea, are key features in this transition.

Student-produced podcasts as an assessment tool: an example from Geomorphology [PDF]

, 2011
The emergence of user-friendly technologies has made podcasting an accessible learning tool in undergraduate teaching. In a geomorphology course, student-produced podcasts were used as part of the assessment in 2008-2010. Student groups constructed radio

Cryptic Ice Wedge Networks in Holocene Peat, Yukon‐Kuskokwim Delta, Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Yukon‐Kuskokwim Delta (YKD), covering ~75,000 km2 of Alaska's discontinuous permafrost zone, has a historic (1902–2023) mean annual air temperature of ~−1°C and was previously thought to lack ice wedge networks. However, our recent investigations near Bethel, Alaska, revealed numerous near‐surface ice wedges.

Lithology and the evolution of bedrock rivers in post-orogenic settings: Constraints from the high elevation passive continental margin of SE Australia [PDF]

, 2010
Understanding the role of lithological variation in the evolution of topography remains a fundamental issue, especially in the neglected post-orogenic terrains.

Modeling Changes in Flow Dynamics From the Restoration of a Distributary Slough Along a Large Floodplain River

River Research and Applications, EarlyView.
ABSTRACT Sloughs are slow‐moving or still water systems that serve as an important ecosystem component connecting rivers and floodplains such as the Apalachicola River in northwest Florida. However, sloughs of the Apalachicola River have become hydrologically disconnected from the mainstem due to the impact of failed navigation projects such as channel

Local economic resilience and economic specialization in Greece during the crisis

Regional Science Policy &Practice, EarlyView., 2023
Abstract This paper scrutinizes the issue of economic resilience, aiming to detect the existence of a systematic link with economic specialization. To this end, the paper conducts an empirical analysis at the local (i.e., municipal) level of Greece during the economic crisis period (2009–2015), providing cartographic visualizations and spatial ...

Prioritization of sub-watersheds of the Kanakapura Watershed in the Arkavathi River Basin, Karnataka, India- using Remote sensing and GIS

Geology, Ecology, and Landscapes, 2021
Prioritization of sub-watersheds is a crucial aspect of watershed management as it may not be possible to execute development programs at a time for entire watersheds in a basin owing to the paucity of financial resources.

Using LiDAR‐Based DEM Elevation Difference Calculations to Estimate Net Streambank Erosion in an Iowa River, USA

River Research and Applications, EarlyView.
ABSTRACT Streambank erosion is an important source of sediment to river systems but is difficult to quantify at watershed scales. In this study, high‐resolution Light Detection and Ranging (LiDAR) measurements collected from 2009 and 2020 were used to quantify the difference in land surface elevation that occurred along the fourth and fifth‐order ...
