OSU NOPP-OCCAM minibat group homepage

The minibat is a towed vehicle with a CTD package on board, similar but much smaller than vehicles like the SeaSoar. It is deployed off of a small boat (in our case, the R/V Sacajawea , OSU's 37 foot small boat).

Updates to the MiniBat group

Cruise diary

9/15

Completes a pair of NH line surveys. A bumpy ride, but a good cruise otherwise! here for details.

9/14

My Fiance and I complete a hydrographic section along the Newport line- how romantic! here for details.

9/05-9/07

Winch overhaul- major lube job.

9/01

our first entirely successful cruise in some time. Data all the way into 8m of water. check here for details.

7/28

Even with a broken depth transducer, the survey must go on. Another NH line, from NH-15 to inside NH-1. The data is here.

7/27

another successful radiator pattern. We got in to the 10m isobath on the NH portion of the cruise (it's still stratified there, even inside the reef!). See the data here.

7/23

I've ordered 30m of cable fairing from zippertubing to see how much good fairing will affect the behavior of the vehicle.

7/21

Another NH line section out to NH-15. See the data here.

7/20

Our first radiator pattern! We did four zonal (E-W) surveys, one along the NH line, one 5km north and a line 5km south twice. In addition, we collected data along the meridional sections. See the data here .

7/15

Tagged along on one of Bill Petersen's Sac cruises. Good section collected. Nice strong upwelling winds the previous few days provide interesting conditions. Vehicle undulates between surface and 62m at 6 knots! Down to 80m with stop & drop. See the data here.

7/14

Cruise cancelled due to rough seas.

7/13

Cruise cancelled due to strong winds, big seas.

7/06

successful cruise with the new wings. here is the preliminary data.

6/30

Today's cruise canceled due to mechanical problems with the R/V Sacajawea.

6/30

The data from the 6/29 cruise is on the web- check it out here!

6/30

the new wings arrive! Hopefully this will buy us much better and easier vertical coverage...

6/29

Our latest survey cruise- with the towbar mounted forward of the wings, we get the instrument to the surface!

6/17

Data from June 15 and June 16 cruise now online!

6/16

Out best cruise yet! good vertical coverage across the shelf.

6/15

Successful engineering/science cruise! We tried several different instrument configurations and managed to coax another 10m vertical range out of the instrument. Check back for data.

6/10

The wing shaft bar was bent during the last cruise- a new stainless steel bar has been ordered. Also, new towpoint holes have been drilled on the Minibat body, forward of the factory supplied ones. This should hopefully improve the towing characteristics.

6/09

Data from the 6/01 cruise is now online! Check it out here .

6/01

Another successful cruise along the Newport line! The new "stop and drop" technique was tested and was largely successful.

5/28

We attempted an "engineering cruise" to try to improve some of the flight characteristics of the minibat, but we got battered by waves instead. We may try again this weekend, depending on conditions.

5/26

I've written a Short note on some interesting water mass properties observed during the last cruise.

5/20

A preliminary look at data from the May 19 cruise! check it out here

5/19

Another successful cruise! Check back Thursday for a summary of the cruise and the data! With ADCP and surface T/S data for the first time!

5/18

Got out to newport, got set up, got outside the jetties, and it was too rough to safely deploy and recover the MB. Aborted cruise. However, we did manage to calibrate the ADCP compass before turning tail.

5/17

Went out to Newport to pick up and set up the SBE-19. Works fine.

5/13

We'll be borrowing Bill Peterson's SBE-19 to use as a thermosalinograph, to fill in some of the info near the surface. We may also do casts in the top 30 meters every so often to fill in some of the surface structure.

5/10

We have a leaky flurometer! The signal from the flurometer looked bad so I had WetLabs check it out. Upon opening the case it was clear we had a leaky instrument. It is being replaced and should be ready in time for the next cruise.

5/6

Cruise details, and date for the Cinco de Mayo (5/5) ocean cruise can be found here.

5/5

Our first really successful cruise! Check back for the data!

4/15

Cruise details, Tax day (4/15) ocean cruise can be found here.

3/17

Cruise details, St. Patrick's day (3/17) test cruise can be found here.

Our vendors:

Guildline instruments built the tow body and the flight software.

We use a Seabird Instruments SBE-25 Sealogger CTD.

It has a Wetlabs WetStar flurometer.
