Abyssal deposit feeders are secondary consumers of detritus and rely on nutrition derived from microbial communities in their guts by Sonia Romero-Romero, Lee C. Miller, Jesse A. Black, Brian N. Popp, Jeffrey C. Drazen

“…We used compound-specific stable isotope ratios of amino acids (CSIA-AA) to estimate the trophic position of three abundant species of deposit feeders collected from the abyssal plain of the Northeast Pacific (Station M; ~ 4000 m depth), and compared it to the trophic position of their gut contents and the surrounding sediments. …”

Ocean warming, icebergs, and productivity in the Gulf of Alaska during the Last Interglacial by Maria Luisa Sánchez Montes, Maria Luisa Sánchez Montes, Erin L. McClymont, Hirofumi Asahi, Joseph Stoner, Christopher M. Moy, Sophie Gleghorn, Jerry M. Lloyd

“…We observe lower %IRDs during cold MIS 6 than during warm MIS 5, and overall lower carbon and nitrogen accumulation rates (TOC and TN MAR) and stable isotope ratios (δ15N and δ13C). We conclude that during MIS 6, the stratification of the cold and fresh surface ocean helped the growth of the CIS, and coccolithophores did not fully exploit the nutrient availability in the ocean but contributed to deep carbon storage and climate cooling. …”
