Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

Journal of Petroleum Geology, EarlyView.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States)

Journal of Phycology, EarlyView.
Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).
