Charlie is ahead of the game
In
the past few days Charlie has migrated 340km further north. Now Charlie and
Nad are both in Bohai Bay, while Charlie is now at a location even
further north than Nad, who has been at
Bohai for more than 20 days.

It is of interest to compare the

Looks
like Nad had used a “quick moving strategy” to get to the Yellow Sea area as
soon as possible, while Charlie spent a bit longer time fuelling up before
moving to the next stop. We can see although it has taken more time for Charlie
to arrive at its current location in Bohai Bay, it has actually travelled
shorter distance than Nad but made a greater displacement from their starting
point in Broome. Let’s see what their next move will be!
