Socioeconomic consequences of cyanobacterial harmful algal blooms in small-scale fishing communities of Winam Gulf, Lake Victoria J. Great Lakes Res. (IF 2.2) Pub Date : 2023-09-30 Julia Akinyi Obuya, Horace Owiti Onyango, Mark Olokotum, Brittany Zepernick, Kaela Natwora, Dennis Otieno, Winny Owoko, Dorine Achieng, Patrick Wanguche Otuo, James Last Keyombe
Lake Victoria has experienced progressive eutrophication which has exacerbated the proliferation of cyanobacterial harmful algal blooms (cHABs). Fueled by anthropogenic nutrient loadings and climate change, these cHABs are increasing in distribution, duration, and frequency, particularly in areas such as the Winam Gulf. With limited resources and infrastructure, local communities have been left vulnerable

Unconsolidated sediment thickness mapping by waterborne geophysics along the Lake Michigan shoreline J. Great Lakes Res. (IF 2.2) Pub Date : 2023-10-01 Sina Saneiyan, Kisa Mwakanyamale Gilkie, Dimitrios Ntarlagiannis, Andrew Phillips, Mitchell Barklage
Mapping unconsolidated sediment at the Illinois Lake Michigan shoreline (ILMS) is complex but vital for sustainable management and use of this dynamic system which undergoes significant redistribution of sand in the littoral transport system over time. To understand erosion and accretion processes it is critical to map the ILMS sediments at high spatiotemporal resolution. Here we used two geophysical

Beach rebuilding period buffers Indiana beach erosion in Lake Michigan J. Great Lakes Res. (IF 2.2) Pub Date : 2023-09-28 Benjamin Nelson-Mercer, Hannah Tomkins, Tasmiah Ahsan, Cary Troy
Recent high-water levels in the Laurentian Great Lakes caused widespread shoreline damage to beaches, homes, and coastal infrastructure. To quantify these shoreline changes and place them in historical context, shoreline imagery was analyzed to determine the magnitude, rates, and spatial variability of shoreline changes along the Indiana shoreline of Lake Michigan. The analysis shows that over the

Morphological variation in extinct Aulacoseira (Bacillariophyta) species from Lake Towuti, with a description of novel species J. Great Lakes Res. (IF 2.2) Pub Date : 2023-09-22 Mariam K. Ageli, Paul B. Hamilton, Andrew J. Bramburger, James Russell, Hendrik Vogel, Satria Bijaksana, G. Douglas Haffner
Recent studies examining the fossil records of ancient Lake Towuti found this tropical lake once had abundant Aulacoseira spp. that no longer exist in the lake. Varying considerably in cell shape and size, these frustules were found deep within the sediments from the early stages of lake formation (>1 My) and formed two population maxima approximately 300 and 400 kya. We examined the morphological
