Humans not up to the task of gaterhing data to answer your research question? What do you do? Use a proxy? Sophisticated technological equipment? An elephant seal?

As the animals swim for thousands of km and dive down to 2,000 m, their tags record details of temperature, depth and the salinity of the water. When the seals pop up to breathe, the computers transmit the information to scientists in Scotland via satellite.
I wonder if they can be persuaded to take up pollen analysis?
