A new approach for incorporating 15N isotopic data into linear inverse ecosystem models with Markov Chain Monte Carlo sampling.

Autor: Michael R Stukel, Moira Décima, Thomas B Kelly

Publikováno v: PLoS ONE, Vol 13, Iss 6, p e0199123 (2018)

Oceanographic field programs often use δ15N biogeochemical measurements and in situ rate measurements to investigate nitrogen cycling and planktonic ecosystem structure. However, integrative modeling approaches capable of synthesizing these distinct

Gelatinous filter feeders increase ecosystem efficiency

Autor: Michael R. Stukel, Moira Décima, Christian K. Fender, Andres Gutierrez-Rodriguez, Karen E. Selph

Publikováno v: Communications Biology, Vol 7, Iss 1, Pp 1-11 (2024)

Abstract Gelatinous filter feeders (e.g., salps, doliolids, and pyrosomes) have high filtration rates and can feed at predator:prey size ratios exceeding 10,000:1, yet are seldom included in ecosystem or climate models. We investigated foodweb and tr

Carbon sequestration by multiple biological pump pathways in a coastal upwelling biome

Autor: Michael R. Stukel, John P. Irving, Thomas B. Kelly, Mark D. Ohman, Christian K. Fender, Natalia Yingling

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-10 (2023)

Abstract Multiple processes transport carbon into the deep ocean as part of the biological carbon pump, leading to long-term carbon sequestration. However, our ability to predict future changes in these processes is hampered by the absence of studies

Salp blooms drive strong increases in passive carbon export in the Southern Ocean

Autor: Moira Décima, Michael R. Stukel, Scott D. Nodder, Andrés Gutiérrez-Rodríguez, Karen E. Selph, Adriana Lopes dos Santos, Karl Safi, Thomas B. Kelly, Fenella Deans, Sergio E. Morales, Federico Baltar, Mikel Latasa, Maxim Y. Gorbunov, Matt Pinkerton

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-16 (2023)

Gelatinous bloom-forming zooplankton—salps—alter microbial communities and quintuple the flux of sinking particles from the surface to the deep, strongly enhancing the ability of the ocean to sequester CO2.

Lateral advection supports nitrogen export in the oligotrophic open-ocean Gulf of Mexico

Autor: Thomas B. Kelly, Angela N. Knapp, Michael R. Landry, Karen E. Selph, Taylor A. Shropshire, Rachel K. Thomas, Michael R. Stukel

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)

The middle of the Gulf of Mexico is stratified and highly oligotrophic, yet there are anomalously high fluxes of sinking particulate matter from the euphotic zone. Here the authors show that lateral advection of organic matter supports nitrogen expor

Micro-/Meso-Scale Distinction and Horizontal Migration of Tintinnid (Ciliophora: Tintinnida) Assemblages in Three Regions Around the North Pacific Ocean

Autor: Meiping Feng, Shiquan Lin, Wuchang Zhang, Chunsheng Wang, Hongbin Liu, Shunyan Cheung, Haibo Li, Michael R. Stukel, John Paul Irving, Na Li

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

We explored the relationships among different tintinnid populations on micro-, meso-, and basin-scales from three regions across the Pacific Ocean, including the Costa Rica Dome (CRD) in the Eastern Pacific Ocean, the Celebes Sea (CS), and the Tokara

Investigating Particle Size-Flux Relationships and the Biological Pump Across a Range of Plankton Ecosystem States From Coastal to Oligotrophic

Autor: Christian K. Fender, Thomas B. Kelly, Lionel Guidi, Mark D. Ohman, Matthew C. Smith, Michael R. Stukel

Publikováno v: Frontiers in Marine Science, Vol 6 (2019)

Sinking particles transport organic carbon produced in the surface ocean to the ocean interior, leading to net storage of atmospheric CO2 in the deep ocean. The rapid growth of in situ imaging technology has the potential to revolutionize our underst
