Comments:
Ahoy Dan,
What's the rush? Is this a homework assignment?
Whales are mammals. They live in the water, but they breathe air.
Like all other mammals, they are warm blooded and they take care of their young for a period of time after giving birth.
The largest mammal alive is a Blue Whale.

Subject: surface zone
Comments:
Whales spend most of their time on the surface because they breathe air and (most of them)eat plankton that live near the surface. The same would be true of dolphins and porposes.
jellyfish stay near the surface too.
sea birds,say, a seagull is an organism often found on the surface.
what are you doing with all this information?

Answering RED,
Thanks for writing.
Go to the web site listed below for great data on ocean temperature.
http://www.gomoos.org/buoy/buoy_data.shtml?buoy_id=44013
You haven't said what part of the ocean you want to know about. If you could be a little more specific, we could probably find more data.
Also, for the benefit of other site visitors, please tell us more about the bethnic and pelagic zones.

Thanks for your message.
Harry's messages and my answers to Harry are just below your message.
You will see where he tells us his latitude and longitude. He abbreviates latitude as "lat" and longitude as "long". The first question is this:
What is Harry's latitude and longitude?
once you have answered that, use the information to answer my second question: Where in the world is Harry?
Good Luck!

Thanks for giving us your latitude and longitude and water temperature. We are at about 41 degrees North and 72 degrees West. The water temperature here is about 2C near shore and 6C offshore. Sunrise today was at 7:12 and sunset at 4:45 giving us about 9 hours and 33 minutes of "daytime".
How does that compare with your location?

Dear Captain Lathrop, the water temp was approx 20 to 23 degrees C. It is
summer here, although summer is usually delayed this far south on the east
coast. We are also in the grip of a severe drought, so no fresh water is
flushing the river systems. The Lat and Long of the Merrica River Inlet is
approx Lat 37 deg 20 min, Long 149-53.

Comments:
Harry,
Thanks for entering our discussion zone with your question about phospheresence. Before we come up with a specific answer to your question, I'd like to ask you and other visitors to describe phospheresence. I will start by saying that it is a mysterious light that appears in the water around a boat. I first noticed it as a child when rowing at night. Pools of light appeared where I dipped the orars into the water and the sight swirlled around each stroke. Has anyone else had an experience with the light I am describing?

The paper weights are one of the prizes. A sail aboard EASY WIND is another. I figure out you deserve the paper weights because of all the work you did tracking down that deer. The trip on the boat is for doing school work related to the voyage. Have you done any projects yet?

Subject: Profile of River Bottom
Comments:
Profile of the bottom (Thames River)
On September 25, 2002, a group of students aboard Easy Wind collected the following data about the depth of water in the Thames River at the Latitude of New London Harbor Lighthouse (41 degrees 19.00minutes North)
The method of collecting this data was simply to steer a course due East from the lighthouse, keeping on the same latitude, but recording every foot of change in depth as we proceeded from the New London to the Groton side of the river. We began these readings when our depth sounder read 19.8 ft and we were at longitude 072 degrees 05.29minutes West. We finished recording when our depth sounder read 7.0 ft and we were at 072 degrees 04.43 minutes West.
Two variables must be considered when comparing this data to other measures of depth in the Thames River. First, Easy Wind’s depth sounder allows for her keel plus one foot of water below the keel so it actually begins measuring 6.5 feet below the surface. For the true depth from the surface of the water, this distance must be added to each depth measurement. Second, These readings were taken at 1100 hours. High tide that day was at 1235 hours.
Here is the data:
Depth (feet) Longitude (degrees + minutes West)
19.8 072 05.29
19.9 072 05.25
21 072 05.18
22 072 05.17
24 072 05.14
25 072 05.05
24 072 05.04
25 072 04.97
26 072 04.95
33 072 04.94
36 072 04.93
37 072 04.92
38 072 04.90
39 072 04.89
38 072 04.88
39 072 04.85
38 072 04.84
33 072 04.82
27 072 04.81
23 072 04.80
22 072 04.77
24 072 04.74
23 072 04.70
22 072 04.69
21 072 04.52
20 072 04.49
19 072 04.47
17.8 072 04.46
15.7 072 04.45
11.4 072 04.44
7.0 072 04.43
To convert this data into a scale drawing of the river, it will help to figure out the distance represented by each hundredth of a degree of longitude. This can be done on a nautical chart using the scale of miles.
The distance covered by this data is approximately one mile--but you will have to calculate it more closely using the latitude and longitudes given.
The lighthouse stands 89 feet above sea level at low tide and the maximum depth recorded here is about 45 feet. Therefore the vertical range of this profile will be about 150 feet while the horizontal range will be about 5,280 feet (one mile). Because of the great difference in these two ranges, if you keep the horizontal and vertical scale the same, the depth data will hardly show up at all. Therefore I recommend exaggerating the vertical scale to ten time the horizontal scale (as is the practice on many maps that show this sort of data.)
It would be great to see a scale model or a scale drawing of the lighthouse, and then another drawing of the same lighthouse with its height exaggerated to the ten times! This would give the audience a grasp of the exaggeration built into the profile. It is also a great lesson to the kids in the meaning of a scale drawing.
good luck with this project

Paul, Lauren and Lucero,
You found the log entry about the deer. That's good, and you think the deer climbed out of the water and got "home" safely. OK.
But you haven't told me which side of the river the deer climbed out of. Was it the New London side or the Groton side? Can you figure that out.
As for the grand prize. I've already written down what it is. You will find what I wrote in the Discussion Zone under the "Guest Book" session. Go back and read all those messages carefully and you will find out about the Grand Prize.

I will give you some hints. I saw the deer in May, 2000. You can find it in one of the May log entries on this web site. Go to "The Voyage", click "ship's log" and click 2000.
Then scroll down until you get to May.
The deer made it safely across the River and climbed out. When she came out was she in New London or Groton?
Read the log entry to find out.

Submarines would be a good topic because many famous submarines have been to the Thames River. Some of them were even built here. During World War II there was a submarine net across the Thames River. One end of it was close to New London Harbor Light. We can see the place it was attached to the rocks when we are out in the boat.
I enjoy studying fish, but I don't get any money for it. I used to fish when I was younger, but I haven't fished for years. I would like to know what kinds of fish are found in the river and how deep they might go.
I have caught a lobster trap by accident while running at night. The rope that attaches the trap to its buoy got wrapped around our propeller shaft. We ran the engine slowly in reverse and it came off.
I haven't gotten sick enough to throw up, but I have felt woosey in very rough weather. It helps to get out in the fresh air on deck and look at the horizon. After a while, the feeling goes away.

Subject: Mako Shark
Comments:
In response to your question about the range of the Mako Shark, I have found some interesting information. Mako sharks are pelagic or open sea sharks. This is why they are not often a threat to humans. They can swim at speeds of 60 miles/hour. They are found in warm and temperate seas, in the Pacific Ocean from Oregon to Chile. Juvenile(young) Makos are common in southern California during the summer months. Some scientists believe that female Mako sharks migrate into San Diego's waters to have their pups. From spring to autumn, pups and 1-2 year old sharks can be found off San Diego's coast, several miles out at sea. Tyler Wild

Comments:
I think the air puck is a good analogy.
Since the air puck works on a solid surface and the birds we are discussing fly over a liquid surface, i wonder whether an air puck would work on a liquid surface and, conversely, have you ever seen birds "looking like pros" in this respect by flying within a centemeter of a solid surface?

Subject: Tropics / Bird flight
Comments:
What marine animals live in the tropics?
The scientific term for where we find specific plants or animals is "range". Range refers to the geographical limits within which you will find a certain species.
One way to ask this question is:
What marine animals have a range that is limited to the tropics?
Some of Sawyer's list probably are limited to the tropics, others have a range that extends far beyond the tropics (Ocra, for instance).
Another way to approach this question is to ask: "What is the range of this marine animal?" What is the range of the Maco Shark?

Comments:
Katie and Tyler, It seems like the birds glide over the water much like an air hockey puck glides over the air hockey table. Is that right? Just that the birds have control of their direction, where as the puck goes according to how it was hit, and the table has a manufactured airflow, whereas the waves and birds create the airflow. What do you think?

Subject: Bird's flight
Comments:
In our response to the bird's flight question we made a error in typing. We meant to say that the area of higher pressure is under the wings, not above. The faster moving air over the top of the wing causes lower air pressure, doesn't it.

Subject: Birds and Bernoulli
Comments:
Tyler and Katie,
Thanks for your clear and thoughtful answer to my question. "Making the bird look like a pro"--well said!
I would say the pressure above the wing is less than the pressure below the wing, causing the wing to move up. This, of course is why a plane flies and a sailboat sails.
In the case of the birds, flying close to the water, a cushon of air is built up between the water surface and the wing tip. This cushion helps the bird keep its wing dry. (I still give the bird a lot of credit--But Bernoulli sure helps it out!)
- Captain Lathrop, Sat Apr 13 15:07:56 2002
Subject: Birds
Comments:
To respond to your question regarding how birds are able to avoid hitting the waves with their wings when they fly close to the surface, we think it's because of Bernoulli's principle, which states that pressure in a moving stream of fluid is less than the pressure of the surrounding fluid. To apply this to the bird's flight, near the water the speed of the air moving over the wings is much greater than in the small space of air under the wings. Therefore, the pressure above the wings will be great enough to cause the wings to lift upward as the bird moves forward. This upward "suction" is greatest as the wing gets very near the wave, making the bird look like a pro!

Subject: Birds at sea
Comments:
On this voyage we have not seen any birds far out at sea. But I have seen them from sailboats when I have been out of sight of land.
They are mostly in flocks, either sitting on the water or skimming close above the water, swooping between the waves. It wasn't until very recently that I understood how a gull-sized bird could bank between moving waves with its wing tips just a fraction of an inch above the surface of the water and not touch. Can you guess how this is possible?
It is noon on Saturday and we are still out of sight of land. We have been so since Wednesday night.
