- Hypoxia: In ocean and freshwater environments, the term “hypoxia” refers to low or depleted oxygen in a water body. Hypoxia is often associated with the overgrowth of certain species of algae, which can lead to oxygen depletion when they die, sink to the bottom, and decompose.
- Marine Science Overview (M.S.O.): Optional add-on component to any boat ride. Includes ID charts, binoculars, pH/salinity probe, wi-fi scope for viewing plankton tow collections, and plankton tow activities.
- Nekton: Animals that swim purposefully through water, can be fish, invertebrates, marine mammals, and cartilaginous fishes likes skates, rays, and sharks.
- Plankton: organisms that are not able to swim against a current. Many are small phytoplankton and zooplankton, but some jellyfish (that are not propelled by the air above them) can be up to 20′ long!
