**Overview**
Lynker Corporation is seeking a **Plankton Taxonomist** to support NOAA Fisheries' SEFSC Population & Ecosystems Monitoring Division (PEMD). This proposed role will provide specialized ichthyoplankton and zooplankton taxonomy, plankton sample processing, data management, analytical support, and scientific expertise in support of NOAA fisheries research and stock assessments. *Hiring for this position will be contingent on contract award.
The SEFSC Population & Ecosystems Monitoring Division conducts fishery-independent surveys and applied research supporting fisheries stock assessments and ecosystem-based fisheries management. This position will support plankton research involving larval fish and marine zooplankton collected primarily in the Gulf of America and will contribute verified taxonomic data to fisheries science and stock assessment activities.
**Responsibilities**
### **Duties of the Plankton Taxonomist will include the following:**
### **The Plankton Taxonomist should have the following:**
The position is based at the SEFSC Laboratory in Pascagoula, Mississippi. Limited work aboard NOAA ships, charter vessels, and/or small boats may be required. The position includes laboratory work involving microscopy, biological specimens, archived plankton samples, digital imaging systems, and preparation of biological samples for shipment.
Facility access is generally available from 6:00 a.m. to 6:00 p.m., Monday through Friday. Work is generally performed five days per week and does not normally exceed 40 hours per week. Work outside normal operating hours and approved overtime may be required in connection with at-sea surveys and other field activities.
Domestic and international travel may be required for or in support of at-sea surveys, project-related workshops, and working group meetings.

**Responsibilities**
### **Duties of the Plankton Taxonomist will include the following:**
- Perform microscopic examination and morphometric and meristic identification of marine fish larvae collected in the Gulf of America to the lowest possible taxonomic level, including family, genus, or species.
- Provide taxonomic verification of previously identified larval fish specimens.
- Use microscope-digital imaging systems to image, identify, enumerate, and measure larval fish specimens.
- Conduct analyses of imaged specimens, including morphometric measurements and shape analyses.
- Conduct life-history analyses of larval fish specimens as needed, including otolith removal, larval aging, and gut content analysis.
- Maintain current knowledge of plankton taxonomy and systematics.
- Participate in ichthyoplankton taxonomy and identification workshops as needed.
- Assist with training other staff in larval fish taxonomy as needed.
- Assist with preparation of specimens for molecular identification and DNA barcoding to verify ambiguous morphological identifications.
- Process plankton samples using standard laboratory methodologies, including sample splitting and aliquoting, displacement volume measurements, and manual sorting of bulk plankton samples.
- Perform microscopic examination and morphometric and meristic identification of marine invertebrate zooplankton collected in the Gulf of America to higher-level taxonomic classifications.
- Scan and analyze invertebrate zooplankton using benchtop imaging systems such as ZooScan.
- Develop invertebrate zooplankton reference libraries used to train artificial intelligence-assisted taxonomic validation platforms.
- Assist with tracking, maintaining, and curating archived plankton samples.
- Assist with preparation of biological samples for ground and air shipment using hazardous materials including dry ice, ethanol, isopropyl alcohol, and formalin.
- Perform plankton survey, ichthyoplankton, and zooplankton data entry, edits, and updates.
- Provide verified identifications and associated plankton data supporting Southeast Data, Assessment, and Review (SEDAR) and other stock assessment forums in support of the Magnuson-Stevens Fishery Conservation and Management Act.
- Update relevant larval fish databases.
- Assist with management of plankton survey data and coordination of plankton data exchanges between the Trawl and Plankton Branch and its SEAMAP and ZSiOP partners.
- Provide ichthyoplankton and zooplankton expertise to other plankton-related research projects.
- Contribute to research proposals, data summaries, manuscripts, technical reports, presentations, and other scientific deliverables.
- Follow SEFSC publication procedures before publication of abstracts or manuscripts and coordinate scientific products with the Trawl and Plankton Branch Chief.
- Support other Trawl a d Plankton Branch, PEMD, and SEFSC activities as needed, including limited service as a Watch Stander on surveys and laboratory and data-management support for survey-related research.
- Participate in public outreach and education efforts as needed.
- Prepare for and potentially present, facilitate, or participate in workshops, scientific meetings, symposiums, and public forums.
