As a result, many nations
require survey vessels to take steps to protect sea life, such as halting surveys if animals are seen nearby or forbidding measurements in particularly sensitive regions or
during certain seasons.
The timeslot is important for a few reasons: firstly shows that are not in their ideal timeslot will score less viewers
during their first
season of airing, sometimes as little as half, and secondly because some adverts
require a show to be in a
certain slot or in its preferred slot, otherwise they get rotated to their worse side.
