The study of marine life and the interactions within ecosystems.

Areas of study within marine biology including biology, chemistry, physics, geology, and engineering.

A significant voyage that mapped ocean floors, advancing marine science.

Originally aimed at studying atolls and plankton but expanded to discover more marine life.

An exploration vessel that greatly contributed to early marine science by discovering new marine organisms.

Phoenicians who navigated using stars and coastlines.

Question, hypothesis, experiment, results, conclusion.

Induction involves observation without experiments; deduction tests theories through experiments.

Research articles that report experiments conducted by scientists.

A study where organisms are observed in their natural habitat without manipulation.

A controlled study where researchers manipulate conditions and observe outcomes in a lab setting.

At least 3-10 replicates are ideal for valid experimentation.

Field experiments study organisms in natural settings; lab experiments control conditions within contained environments.

Density of seawater is affected by salinity and temperature; cooler temperatures increase density.

Seawater has approximately 35 ppt of salt with ion proportions remaining constant across locations.

Turbidity is influenced by organic and inorganic particles such as sediment and phytoplankton.

Oxygen decreases with depth; highest at the surface due to primary production.

Deflection of wind; right in NH, left in SH due to Earth's rotation.

Three major atmospheric circulation patterns based on latitude.

The spiral pattern of water flow resulting from wind and the Coriolis Effect.

Global ocean current system mixing waters every 1000 years.

Wave energy moves forward while water molecules move in circles.

Factors include wind velocity, duration, fetch, and original sea state.

An unexpected, huge wave created by the interaction of wave systems.

Organic material that cannot be filtered out of water.

Organic material that can be filtered and dissolved in water.

The pathway of dissolved organic carbon through microbes to larger organisms.

Viruses have genetic material and a protein coating, sometimes with appendages.

Bacteria decompose, sequester carbon, and can cause diseases.

Photosynthesizing bacteria that contain chlorophyll a and other pigments.

A harmful algal bloom causing toxicity in water, affecting marine life and humans.

Single-celled organisms with pseudopodia, found in calcareous ooze.

Gravitational and centrifugal forces from the moon and sun causing tides.

Tides caused by the alignment of the sun and moon, resulting in varying tide heights.

One full tidal cycle lasts approximately 24 hours and 50 minutes.

A phenomenon where a flood tide enters a river valley, causing a rapid increase in water level.

Water moves from low to high solute concentration.

Organisms that cannot tolerate wide salinity ranges and match internal salinity with the environment.

Turtles excrete excess salt using specialized salt glands.

For poikilotherms, increasing temperature from 70-80°C raises the rate of enzyme reactions, up to a limit.
