Baseline information: Information gathered over time with the goal of being able to compare it to data collected in the future and conclusions about trends or changes can be made.

Bony fish: A classification of fish with a skeleton made of bone such as salmon, cod, pollock, etc.

Cartilaginous fish: A classification of fish with a cartilage skeleton such as sharks and skates.

Citizen science: Engagement of citizens in scientific research typically by recruiting volunteers to observe or measure specific data of interest.

Climate change: A significant and lasting change in weather patterns, average temperature, or seasonal occurrences as compared to previous climate records.

Conservation: The act of preserving, protecting, or restoring the natural environment.

Crustaceans: A classification of animals with hard exoskeletons such as crabs, shrimp, or barnacles.

Environmental stewardship: The view that humans have a responsibility to care for the health of the earth as a whole.

GIS: Stands for Geographic Information System and is used for linking a set of data points with an exact location.

Latitude: Degree lines used for determining location (along with longitude) that runs east/west across the globe.

Longitude: Degree lines used for determining location (along with latitude) that runs north/south across the globe.

Non-indigenous species: A species established in a location other than its regular habitat, brought in intentionally (i.e. as a pet) or unintentionally (i.e. on the hull of a boat) that has the potential to disrupt the native ecosystem.

Pinnipeds: A classification of marine mammals with front and hind flippers such as seals, sea lions, and walrus.

Prototype: A first model of a project to test its effectiveness and determine what changes need to be made.

Range extension: When a species travels to areas where it would normally not be found as a result of temperature changes, habitat loss, or variations in food availability.

Sea ice variation: Differences in sea ice location, thickness, and seasonal appearances/disappearances in comparison to years in the past.

Stakeholder: A person, a group of people, an organization, a government, or a company with a common interest in finding a solution to a problem.
