Ice-nucleating particles in Greenlandic glacial outwash plains

Nora Bergner, G. Alex. Marsh, Kevin R. Barry, Larissa Lacher et autres

High-latitude dust (HLD) represents a source of ice-nucleating particles (INPs) with potential impacts on cloud formation and radiative forcing in the Arctic. Previous studies have shown that HLD can exhibit high ice-nucleating activity at high subzero temperatures, likely linked to a biological …

Soil microbial diversity, succession, and greenhouse gas cycling across a Greenlandic glacial chronosequence

G. Alex. Marsh, Massimo Bourquin, Alanna Leale, Lisa Bröder et autres

Accelerated glacial retreat in Greenland drives increased development of glacial outwash plains. These newly exposed landscapes provide an opportunity to study microbial dynamics during soil development. We explore soil microbial diversity, community assembly, and biogeochemical cycling across the Kiattuut Sermiat glacial chronosequence …

Microbial dynamics in rapidly transforming Arctic proglacial landscapes

G. Alex. Marsh, Darya Chernikhova, Stefan Thiele, Ianina Altshuler

Arctic glacial environments are rapidly changing, as the Arctic warms at a rate three to four times faster than the global average (the phenomenon known as Arctic amplification). Microorganisms are uniquely adapted to extreme glacial environments and studying how ecological and climatic …

Benthic Faunal Colonization of an Offshore Borrow Pit in Southeastern Florida. Dredging Operations Technical Support Program

Philip R. Bowen, G. Alex. Marsh

Abstract : When sediments are dredged offshore, either for a Corps project or a permitted activity, borrow pits are created. As part of a program to examine the environmental effects of dredging, this study addresses concerns about the changes that may occur …

Benthic fauna of an offshore borrow area in Broward County, Florida / by David B. Turbeville and G. Alex Marsh ; prepared for U.S. Army, Corps of Engineers, Coastal Engineering Research Center.

David B. Turbeville, G. Alex. Marsh

E. nttens at one of the control stations in June.Although faunal similarity analysis revealed a qualitative change in the fauna of the borrow area, this change is not considered detrimental.Conspicuous patterns of heterogeneous faunal distributions were evident in this study, particularly for …

Benthic Fauna of an Offshore Borrow Area in Broward County, Florida.

David B. Turbeville, G. Alex. Marsh

Benthic fauna from two stations within a 5-year-old borrow area and two control stations off Hillsboro Beach (Broward County), Florida, were sampled quarterly from June 1977 to March 1978 to evaluate the long-term impact of offshore dredging. Generally enhanced productivities occurred within …

Ecological Evaluation of a Beach Nourishment Project at Hallandale (Broward County) Florida. Volume II. Evaluation of Benthic Communities Adjacent to a Restored Beach, Hallandale (Broward County), Florida.

G. Alex. Marsh, Philip R. Bowen, Donald R. Deis, David B. Turbeville et autres

Benthic communities adjacent to a restored beach at Hallandale (Broward County), Florida were analyzed and compared to similar communities at nearby Golden Beach (Dade County). Five sand stations and four reef stations were sampled at each locality along a transect from the …
