6 The portion of the ocean that is shallow enough for sunlight to penetrate, allowing photosynthesis to occur. Most life lives in this part of the ocean.
7 Technology that continuously provides information about new life forms, Earth resources, and geologic processes. Examples: SONAR, ROV, Submersible, Buoys, etc.
9 The most diverse marine biome on Earth, found in warm, shallow waters beyond the shoreline.
13 The portion of the ocean that lacks sufficient sunlight for photosynthesis; permanently dark.
