Moritz Schmid

(2017-) Postdoctoral Scholar schmidm@oregonstate.edu

Moritz obtained a M.Sc. in International Nature Conservation, which included studies in New Zealand, Germany and the United States. For his M.Sc. thesis he worked on pan-Arctic species distribution modelling of zooplankton using machine learning techniques, and predicted present day spatially explicit distributions as well as future occurrences and depth distributions based on IPCC scenarios. After finishing this work at the University of Alaska Fairbanks under supervision of Falk Huettmann, Moritz commenced a PhD in Oceanography under the supervision of Louis Fortier at Université Laval, Canada. This PhD was embedded in the wider ArcticNet research network as well as the Canada Excellence Research Chair in Remote Sensing of Canada’s New Arctic Frontier.

For his PhD Moritz utilized the LOKI underwater imaging system on several Arctic research cruises onboard Canadian and American icebreakers. Work for this PhD included the development of a copepod-stage-specific automatic zooplankton identification model. The model was then used to automatically identify underwater imaging data of 1 m vertical resolution for two ecological studies, which focused on the role of lipids in triggering migration to diapause in Arctic copepods, as well as the fine-scale vertical coupling of copepods with their phytoplankton food.

Moritz joined the Plankton Ecology Lab at the Hatfield Marine Science Center, Oregon State University to further work on underwater imaging and plankton ecology using the In Situ Ichthyoplankton Imaging System (ISIIS). This includes the methodological advancement of underwater imaging and automatic identification, as well as studying the ecology of zoo- and ichthyoplankton in the Straits of Florida and off the Oregon Coast.

Miram Gleiber

(2014-) PhD Candidate  gleiberm@oregonstate.edu

I am a PhD student working with the Sponaugle-Cowen Lab on an NSF-funded project: Observations of Subtropical Trophodynamics of Icthyoplankton in the Straits of Florida (OSTRICH). I am studying how small- to large-scale patchiness of zooplankton prey influence the larval fish community, and their predator-prey dynamics. I will be examining larval fish gut content, recent daily growth from otolith microstructure, and lipid composition to infer biological consequences of patchiness on larval fish growth and survival.

My research at OSU is both a taxonomic and geographic transition from my prior work in zooplankton ecology. I completed a Master’s degree with Dr. Deborah Steinberg at the Virginia Institute of Marine Science studying long-term changes in the Western Antarctic Peninsula copepod community, due to rapid regional climate change. I also examined the role of copepods in carbon cycling, through grazing of phytoplankton and fecal pellet production and export.

Daniel Ottmann

(2014-2016) MS  ottmannd@science.oregonstate.edu

Dani’s MS research is focused on the settlement of rockfishes and Cabazon to the Oregon coast. He is collaborating with Dr. Kirsten Grorud-Colvert (OSU), the Oregon Department of Fish and Wildlife, and the Oregon Coast Aquarium to examine patchiness in juvenile recruitment to marine reserves and non-reserve comparison areas off the coast of Oregon.

 

Will Fennie (2015-) PhD Student hfennie@mlml.calstate.edu

Will came to OSU after completing a Masters in Marine Science at Moss Landing Marine Laboratories (MLML). At MLML, Will worked with Scott Hamilton and  studied the effects of elevated CO2 on the behavior and physiology of juvenile rockfishes. There he found that different species of rockfish differed in their response to CO2 and that early life history characteristics of rockfishes influence their response. Will is excited to continue studying the early life history of rockfishes at OSU with Su Sponaugle. Here he hopes to understand how environmental conditions experienced during larval and pelagic juvenile phases affect the diets, growth, and post settlment mortality of Oregon's rockfishes. Will is also interested in understanding how Oregon's marine protected areas affect the diets, growth, and mortality of settled juvenile rockfishes.

 

Kelsey Swieca (2016-) PhD Student swiecak@oregonstate.edu

Kelsey joined the Sponaugle Plankton Ecology lab Summer 2016. Her PhD research will utilize the In Situ Ichthyoplankton Imaging System (ISIIS) to investigate fine-to-coarse scale distributions of recreationally, commercially and ecological important larval fish in the California Current. 

 

 Kelia Axler (2016-) MS Student axlerk@oregonstate.edu

Kelia joined the Plankton Ecology lab in the fall of 2016 after spending a few years working in the Gulf of Mexico on a variety of post-oil spill assessments. Her MS research will examine the influence of pulsed-river plume events and seasonal hypoxia on the spatio-temporal distributions, growth, and survival of larval fishes in the northern Gulf. This research will contribute to an improved ability to predict the impacts of environmental disturbances (e.g., oil spills) on the highly sensitive, early life stages of regionally and economically important fish communities in the hydrographically complex northern Gulf.

Dr. Kelly Robinson 

(2014-2016) Assistant Professor of Coastal Biology, University of Louisiana at Lafayette, kelly.robionson@louisiana.edu

I collaborate with the Sponaugle/Cowen Lab on their NSF-funded project: Observations of Subtropical Trophodynamics of Ichthyoplankton in the Straits of Florida (OSTRICH). I have a doctorate in marine science from the University of South Alabama and a Master’s degree in fisheries and aquatic science from the University of Florida. My research interests as a coastal biological oceanographer are broadly aimed at the effects of climate-driven processes on marine zooplankton production and distribution, with an emphasis on gelatinous plankton predators (i.e. jellyfish). I am particularly interested in how climate forcing alters trophic interactions and energy transfer between marine zooplankton groups, planktivorous fish, and their predators. To address questions related to this topic, I use a combination of experimental lab work, field studies, and modeling (including spatial analysis and food web modeling). For the OSTRICH project, I am examining using DPI images: 1) at what scales are organisms (larval fish, prey, and predators) aggregated, or random, 2) how fine-scale patchiness scale up in different environmental conditions and physical settings, and 3) if patchiness of larval fishes scale with that of their prey and predators. I have also been involved with the National Data Science Bowl, a machine learning competition to improve automatic plankton image classifications.
