What type of large-scale ocean current is primarily driven by differences in water density, caused by variations in temperature and salinity?
What is the primary gas released by phytoplankton during photosynthesis, contributing significantly to the Earth's atmosphere?
What is the general term for the microscopic, drifting animal life in the ocean, which includes the larval stages of many larger marine organisms?
What are the specialized cells in cephalopods (like octopuses and squids) that allow them to rapidly change skin color and texture for camouflage and communication?
