OIB: Across the Ross

The video discusses a NASA mission to survey the Ross Sea using laser and radar technology. The mission aims to understand the movement and thickness of sea ice, which is crucial as the Ross Sea is one of the few areas where sea ice coverage is increasing. The NASA P3 aircraft conducted the survey, encountering challenges like icebergs and fog. The data collected will help determine if the increased ice area corresponds to a greater volume of ice.

What was the main reason for conducting the first comprehensive survey of the Ross Sea?

• To take advantage of unusually clear skies

• To explore new shipping routes

• To measure the impact of pollution

• To study the wildlife in the area

What was the primary objective of the NASA P3 aircraft's mission?

• To photograph the coastline

• To map the ocean floor

• To sample the movement of sea ice

• To study atmospheric conditions

What challenges did the team face during the mission?

• Severe storms

• Equipment failure

• Large icebergs and open ocean leads

• Communication issues

Why are the leads in the sea ice considered valuable for research?

• They are indicators of climate change

• They help in estimating sea surface temperature

• They provide a habitat for marine life

• They allow for the estimation of sea ice thickness

Why is the Ross Sea particularly important to study in terms of sea ice coverage?

• It is home to unique marine species

• It is a major shipping route

• It has been experiencing a decrease in ice coverage

• It is one of the few areas with increasing ice coverage
