100

Large-scale changes that result in the formation of new species.

What is macroevolution?

100

Ancient Pacific navigators used stars, waves, and birds to find their way.

Who were the Polynesians?

100

Order the ocean zones from shallowest to deepest.

What is Epipelagic → Mesopelagic → Bathypelagic → Abyssopelagic → Hadalpelagic?

100

Algae type with chlorophyll pigments found in shallow waters.

What is green algae?

100

This process drives ocean circulation by differences in temperature and salinity, helps distribute heat around the planet, and is influenced by changes in climate.

What is thermohaline circulation?

200

Fossils showing intermediate traits between species and evolutionary links.  

What are transitional fossils?

200

First to circumnavigate the globe.

Who was Ferdinand Magellan?

200

How light, temperature, and pressure change with depth.

Light decreases, temperature drops, and pressure increases with depth.

200

Algae type with fucoxanthin pigment found in cooler waters.

What is brown algae (e.g., kelp)?

200

How phytoplankton affect the carbon cycle.

They absorb CO₂ and transfer it to the deep ocean (biological carbon pump).

300
An extinction event with the slow, steady loss of species. 

What is background extinction?

300

Known as the “Father of Modern Oceanography” for mapping ocean currents.

Who was Matthew Maury?

300

The system that uses sound waves to measure depth.

What is SONAR?

300

Algae type with phycoerythrin pigment found in deep tropical waters.

What is red algae?

300

Burst of phytoplankton caused by excess nutrients in the ocean. 

Harmful Algae Bloom

400

How water first appeared on Earth.

What is delivery by comets/asteroids and outgassing from volcanic activity?

400

This naturalist studied ocean currents and inspired future explorers.

Who was Alexander von Humboldt?

400

Order of ocean floor features from coast to deep.

What is Continental Shelf → Continental Slope → Continental Rise → Abyssal Plain?

400

The base of the marine food web.

What are phytoplankton?

400

Difference between ROVs and AUVs.

ROVs are remotely controlled by humans, AUVs are pre-programmed and autonomous.

500

The first life forms and where they appeared.

What are simple, single-cell microbes (bacteria/archaea) found in oceans or hydrothermal vents?

500

The first global oceanographic expedition that discovered deep-sea life and mapped the seafloor.

What was the HMS Challenger Expedition?

500

The process that brings nutrient-rich water to the surface.

What is upwelling?

500

The difference between holoplankton and meroplankton.

Holoplankton stay planktonic their whole lives; meroplankton are planktonic only as larvae.

500

The submersible that explored hydrothermal vents and the Titanic.
