Thanks for responding. We will see who is right when Roz arrives at her final destination: Tuvalu, or somewhere nearby, later this summer.
Now for this week’s question: We all think of Roz as being over deep ocean water, but you may be surprised to learn that some of the ocean she is sailing over is relativly shallow. As of Wednesday, June 24th, Roz is near a feature called the Harrision Seamount. The water she is over is much shallower than the ocean she has been traveling on. So for this week, what is a seamount? What causes them to form? Will Roz notice a difference?

Roz may see and not see many of the creature in her area. Marine mammals, such as whales and dolphins will be easy to spot. Why? Because they need to come to the surface to breathe. Roz may also spot flying fish, which jump out of the water and may become stranded on her deck. She may catch glimpses of other fish jumping, such as tuna, but most other fish will stay below her boat and may be out of sight.
That being said, Roz is now in tropical oceans. The open ocean tends to be less productive in the tropics (fewer microorganisms is part of the reason the tropical ocean is so clear). The most important and productive ecosystems in tropical seas are in coral reefs, which tend to form in shallower waters.
Now for today's question: Look at the statistics on the Roz Tracker. Roz is attempting to row from Hawaii to Tuvalu. 2,620 statute miles in all. When do you think she will arrive in Tuvalu? Post your predictions to this blog!

What's Under the Boat??
Environmental problems in Roz's part of the ocean are a huge issue. Garbage from land - even land far from the sea - can work its way down streams and rivers and pollute even the most remote parts of the ocean. Click here to learn how. There are other problems effecting her part of the ocean as well. Look up works like overfishing and destructive fishing practices to find out more.
...and now for this week's question: Find Roz's position on the map. What sea life is likely to be around her? Which of those creatures might she be able to see and which not?
