The Hudson River National Estuarine Research Reserve (HRNERR) seeks a student intern to assist with a trail planting of water celery (Vallisneria americana), a species of Submerged Aquatic Vegetation (SAV). Water celery is valued for providing habitat for fish and for improving water quality. The cover of water celery was greatly reduced in the Hudson River following storm events, and areas that have not recovered naturally have been mapped. HRNERR has started a project where water celery has been cultivated in a greenhouse. By participating in this internship, the student will help plan and implement an experimental design for planting this cultivated water celery within a freshwater tidal Hudson River Research Reserve site. The student will also gain experience with standard protocols used to collect water quality, nutrient, and weather data. In addition, this position may support tasks including how to safely store, handle, and dispose of chemicals, clean glassware, and prepare chemical standards. Other potential internship duties include river water sampling (from shore or boat), assisting with laboratory protocols (filtering and weighing), and calibrating instruments.
