Glacial Expansion of Deoxygenation in the Arabian Sea

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The mechanisms by which ongoing climate change influences ocean Oxygen Minimum Zones (OMZs) are insufficiently understood, making it essential to examine their long‐term variations under substantial climatic forcing. Here, we present the first planktic foraminifera iodine‐to‐calcium records in two Arabian Sea sediment cores: one located within

Halogenated Organic Compounds: A Massive Halogen Reservoir and an Intriguing Component of the Marine Dissolved Organic Matter Pool

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Biogeochemical reactions produce volatile halocarbons and semi‐ to nonvolatile dissolved organic halogens (DOX) in marine systems. The former has a large influence on atmospheric chemistry, but little is known about DOX. Here, we present depth profiles of dissolved organic bromine (DOBr) and ‐iodine (DOI) isolated from the Central North ...

Surface Inorganic Iodine Speciation in the Indian and Southern Oceans From 12°N to 70°S

Frontiers in Marine Science, 2020
Marine iodine speciation has emerged as a potential tracer of primary productivity, sedimentary inputs, and ocean oxygenation. The reaction of iodide with ozone at the sea surface has also been identified as the largest deposition sink for tropospheric ...

Accessing the impact of harvest weights of Tenebrio molitor on amino acid digestibility and metabolizable energy in cecectomized laying hens

Journal of the Science of Food and Agriculture, Volume 106, Issue 1, Page 665-674, 15 January 2026.
Abstract BACKGROUND The effects of harvest weights on composition, amino acid (AA) digestibility and metabolizable energy (MEN) of Tenebrio molitor (TM) were investigated using cecectomized laying hens. The partially defatted and dried TM variants comprised median individual frass‐free harvest weights of 60, 80, 100, and 120 mg of larvae, and a pupae ...
