What is the primary function of the CTD tags used on sharks in the described research?

To measure ocean conductivity, temperature, and depth for hurricane modeling

To track the migration patterns of sharks across the Atlantic

To monitor the health and stress levels of shark populations

To identify the breeding grounds of protected marine mammals

In the context of hurricane intensity, what is the significance of the ocean's 'mixed layer'?

It contains the heat energy that fuels the intensity of hurricanes

It is the deepest part of the ocean column unaffected by surface winds

It is the layer where salinity is at its lowest point

It acts as a barrier that prevents the formation of tropical cyclones

Sharks used for hurricane predictions

This topic provides a novel technological application for disaster management and climate monitoring, serving as useful context for answers on cyclone prediction and environmental technology.

Notes

University of Delaware researchers are using sharks as mobile, near-real-time ocean-data observers to improve hurricane intensity predictions.
Sharks are equipped with CTD (Conductivity, Temperature, and Depth) tags that measure ocean salinity, temperature, and depth.
Data collected focuses on the 'mixed layer' of the ocean, which stores the heat energy that fuels hurricane intensity.
Sharks are chosen for this research due to their abundance, wide distribution, and ease of access compared to marine mammals.
Candidate species for tagging in the North Atlantic include shortfin mako, blue sharks, smooth hammerheads, and juvenile great white sharks.
Tags are attached to the dorsal fin and transmit data to satellites when the shark surfaces.
The tagging process is conducted under institutional animal care oversight, using materials that corrode and fall off, and includes health checks to ensure natural behavior.

Part of a longer story

This is day 2 of 2 in Use of shark-mounted sensors for hurricane intensity forecasting, which has been running since 11 August 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
