Hi all: In a few weeks we will open a bid to acquire a couple of Doppler profilers. We have been using RDI instruments for LADCP use since 2004, and although...
Sorry, I missed the correct 'subject' field in the earlier message. Best regards, Ricardo. Instituto Español de Oceanografía - IEO ... Subject: More about...
Ricardo, I have had brief contact with Linkquest, with the idea to test their instrument for lowering. However, we could not come to a mutually beneficial...
Thanks Lisa. Considering the problems we already have with RDI instruments, the fact that the LinkQuest has not yet tested theirs for LADCP is discouraging -...
Ricardo, You will have to ask LinkQuest whether they have a means of synchronizing the pings from a pair of instruments. (If you got a 150-kHz instrument, then...
Actually, it's not on one of my moorings, but is deployed in a trawl- resistant bottom mount in the Karimata Strait, Indonesia, depth 40 meters. Dwi Susanto...
Hi guys! We were in a cruise where some persons recorded accidentally configuration files to Master and Slave ADCP switched before deployment (this is...
Hi David, It really shouldn't matter which instrument is set as master (triggers the other one to ping) and which is set to slave (waits for trigger to ping)....
Hi David and Lisa, I agree with Lisa. In our processing version there is no distinction between Master and Slave but only between UP and DOWN ! So you should...
Hey there! I need some help! I have lADCP data of an 1200 kHz RDI Workhorse (Burst Mode 12) and I'm looking for a hard formula to calculate the accuracy of my...
... In the Lamont version (based on Visbeck's implementation) switched files are detected automatically (in loadrdi.m), i.e. there is no need to switch the...
Hi all, Does anyone have code to calculate Scattering Cross Section (usually denoted by sigma, in units of 1/m) or Scattering Strength (Usually denoted by Sv,...
... Yep, that's true. In fact I could process just one of the "bad station" swapping the data, but doing so with the other ones gives me several errors in the...
Hi... Well I explain again the problem more detailed. In a cruise we collected data from LADCP and CTD during 117 stations. For the 31 first stations, I can't...
Hi David, I will have a look at your problem. I am however currently at the EGU meeting and might not find a free moment until mid of next week. Cheers Gerd...
Hi All, Any opinions yet on RDI's "new build process" transducers that are supposed to survive pressure cycling longer? Any idea whether range or data quality...
James, Too early to say. Lisa is at sea on the first test of the first one right now, with a moderate number of cycles. So far, so good. No transducer...
Hi James, I am presently out in the subequatorial Atlantic testing Eric Firing's prototype WH300 with the new transducer build. I'll let Eric give specifics at...
Hi David and all others, I dug into his data and after some 45 minutes found that d.down.Single_Ping_Err = 0.64 m/s On all my data and also on his uplooker...
Gerd & David, ... You are right. The single ping error is estimated from the scatter in vertical velocity in bins 2-6 in loadrdi.m, i.e. a large single-ping...
Andreas, I did not use any other program but already from the normal routines it is obvious that ONE bin, #3, is constantly bad. Large echo amplitude etc... I...
Hi Gerd, First of all I would like to give you my and all the ULPGC's ocean research group gratitudes for your help and work. When u say "command files", what...
Hi David, Here is a compiled scannbb for linux. I know that is not exactly what you are looking for but it is all I have. Hope that helps. DT ... -- Daniel J....
Gerd, ... Interesting. The only time I have seen something similar is when we tried to use a steel ball as a CTD bottom-detection switch. The sidelobe echo...
Hi David, ... This is a misunderstanding: scanbb is part of Eric Firing's software and has nothing to do with me. But I do have pre-compiled versions for the...
Hi David, yes those were the files I was asking for. Haven't had a look at them yet. For the problem with the other files, I might have a solution. Please try...
Hello Andreas and Gerd, I have been following all of this and I have a question regarding this situation. Is bin 3 bad through out the entire profile or is it...
Hi Darryl, I looked primarily at the data from one cast (25). In this cast, bin 3 of the downlooker looks suspicious. I attached a figure showing the echo...
