OASIS Change Log Created March 1, 1992 Please note all changes to the M1 mooring, the OASIS controller, or any equipment that resides on M1 in this log. Sign and date your entry. The initials "rah" are for Robert A. Herlien. For a log of all radio contact with OASIS, see the blue notebook labelled "OASIS Radio Log". It normally resides in the microwave room on the second floor of 160 Central. 16jan92, rah OASIS deployed on M1 mooring. 17jan92, rah Created /usr/local/oasis directory on hp850, to receive oasis data. The "decode" program uses file /usr/local/oasis/raw/oasis.cfg for its configuration, which in turn references files /usr/local/oasis/src/cable01a.coef for ATLAS calibration, and file /usr/local/oasis/src/ctd.cal for CTD calibration. 05feb92, rah Francisco visited M1 on Pt. Lobos; swapped spectroradiometer cables, so that OASIS now reads the 10 meter spectro. 19feb92, rah Changed ADCP to 1200 baud. 26feb92, rah Francisco et al visited M1. Removed surface and 10 m spectros. Swapped CTD, replaced with serial number 195114-0868. Also swapped fluorometer, transmissometer, air temp sensor. Bob changed oasis.cfg file to reference CTD calibration file /usr/local/oasis/src/ctd.868. 28feb92, rah OASIS not responding since evening of 26 feb. Gary et al visited M1 on Ridgeway, recovered OASIS controller, and brought it back to the lab at 160 Central. Problem later determined to be blown chip in DC-DC converter circuit. 10mar92, rah OASIS redeployed at M1 with version 1.3 of OASIS software. Changes in version 1.3 of software: 1) New defaults (30 sec. avg for PAR, some others) 2) New way to check if powered down properly 3) Resets entire system if not contacted for 24 hrs. 4) New PwrTemp parameter 5) Spectro driver eavesdrops only (doesn't ^C, J cmd) 6) Changed serial input buffer to 756 bytes, for ADCP 7) New "analog" command to get A/D value 13mar92, scri Reset adcp to 9600 baud. Adcp came up with Mar 14th for date it obviously missed the leap-year. All data from 1-Mar to 14-Mar needs to be corrected back one day. 16mar92, rah Debugged "getm1" program to automatically download every 2 hrs Started cron file for 2 hour download. 19mar92, rah Francisco et al. visited M1. Replaced CTD with serial number 195300-099. Bob changed oasis.cfg file to reference CTD calibration file ctd.099. 19mar92, scri ADCP still dropping data, went back to 1200 baud. Last old cycle should be at 03:19:21:12:30. First new cycle should be at 03:19:22:15:00. 25mar92, scri Not getting ADCP, connected to adcp @19:24:10 Bob found drvprm 'extra 1' = 0, should be 45. ADCP set to restart at 03:25:19:45:00 31mar92, rah 00:02 OASIS stops receiving ADCP data (cause not determined) 08:48 ATLAS goes into deployment mode (presumably from reset) 15:08 I connect to OASIS, do a "sync" 15:18 OASIS resumes receiving ADCP data 20:18 OASIS stops receiving ADCP data 20:48 ATLAS returns to normal mode (as it should after 12 hrs) 01apr92, rah 00:48 ATLAS goes into deployment mode 02:58 ATLAS stops responding to OASIS 08:37 ADCP relay select wrong. I fixed it & "sync"d. Attempted to connect to ATLAS. It will not respond. 13:15 Francisco (on Pt. Sur) cycled power to ATLAS Started getting ATLAS again, log memory error. 07may92, rah Francisco visited M1, replaced CTD with 195114-0868 and reconnected spectroradiometer. Changed oasis.cfg file to reference ctd.868. Changed spectro time to 10 minutes, manually set PAR collection time to coincide with spectro. 12may92, rah Rewrote `decode`, `extract` to convert spectro to real units. Re-extracted data from days 128 to present. 14may92, rah Extracted data from CTD files recovered from CTD's at turnaround time. Overwrote OASIS data in /usr/local/oasis/ctd with data from CTD's themselves. OASIS data is available on tape from Bob if anyone needs it. 27may92, rah Spectro stops sending data. Efforts to talk to it fail. Presumed dead battery. Last battery voltage sent was 29.61 V. 29may92, rah Francisco (at M1) disconnects 10m spectro (#8271) from OASIS, connects 20m spectro (#8270) 30jun92, rah Extracted data from CTD files recovered from CTD 868. Overwrote OASIS data in /usr/local/oasis/ctd with data from CTD. OASIS data is available on tape from Bob. 11Aug92, peti: Below is appended Pennington's log of OASIS swapouts and so on. I have now abandoned my independent log, and will in future make my entries here as rah has done. LOG OF OASIS EQUIPMENT SWAPOUTS (JT Pennington) EQUIPMENT SET A: CTD 99 SET B: CTD 868 Trans 277 Trans 485 Fluor. 41 Fluor. 79 Jan 16, 92: Initial deployment of mooring plus equipment Set A Feb 23?: M2; change ATLAS batterys Feb 26: Deploy Set B; return Set A to lab. Return Spectro's 8720 and 8707 to lab Change air temp sensor Feb 26: Oasis can failure Mar 10: Oasis can redeployment Mar 19: Redeploy Set A; return Set B to lab April 15 or 19: Clean equipment in situ; see handwritten notes. May 5: In air @ 160 Central reading of Trans 485 was 4.52 volts May 7: Deploy Set B; return A to lab Deploy Spectro's: 8721 (10 m) Spectro 8720 (20 m) Spectro 8708 (surface) All the spectro's have new alkalines, and Menzies downloaded 870 8, and apparently took the data with him. The 2 barnacle settlement plates had 0 recruits, and this was in line with the lack of fouling observed. However these plates were just at the surface. The 3 new plates installed are about 1 ft deep. June 5 : Labwork--- cleaned Set A after SU92-2 Drifter deployment; set CTD clock on GPS time; set CTD sample interval to 600 sec; CTD sampling on the 10 min mark (ie, 1200, 1210, 1220...) will have all equip repainted with copper refurbished trans and CTD zinks JUNE 12, 1992 (16492): After an abortied (rough) Pt Lobos day June 8, made a Ridgewa y run 6/12 Pennington, Etch., T3 Glassy calm w/ no swell Did topside cleaning and swapout: SET B to shore; SET A deployed. Fouling was mostly bryozoans or hydroids; few barnacles and no m ussels On my 3 barnacle plates I got 1 Lepas; I deployed 3 more plates Trans zinks were almost gone; CTD zinc OK but I replaced it. Cleaned the instruments and downloaded and QL'd the CTD June 17: Pt Lobos to mooring; moderate weather; tied to mooring Penn, Menzies, divers Replaced clay top on humidity sensor; old one seemed clean; no salt observed Divers cleaned 20 m spectro; little fouling noted Divers checked spectro depths---they were very close to 20 and 10 m Divers removed 10 m unit; noted barnacles hanging over it on tether Menzies could not communicate with 10 m unit; had to reset it; then it seemed as if it were running all along; found problem with headers; he replaced tape and attempted download RAM. He reloaded programs and got it running Divers redeployed it; strong current; tim dropped RS232 cable into water but it dried OK Menzies found 6 volts across red switch wires, confirming electical connection to unit, but he was unable to communicate with it We left it, occupied 2 CTD stations, and went home. Jul 23: Pt Sur to M1, then M2; Full compliment of personel (see cruise plan) Weather glassy to M1, then up to 25 kt wind and 8-10' swell to M2 Fired release, lifted M1 OASIS onto deck, cleaned barnacles, spooled tether There were 4 Lepas recruits on my 3 plates; this is about right considering the light fouling of recent recruits elsewhere on the mooring Returned sensor SET A to lab; downloaded CTD My zinks are about 1/3 gone; ACDP zinks, which have never been swapped, are barely eroded ADCP, coated with plastic, is also not very fouled Took a short CTD/trans/fluor cast at M1; this data on floppy only Repeated process with M2 ATLAS Begin process of refitting and addiction of new sensors for Aug 19 redeployment Jul 31: Calibrated transmissometers in air, with cleaned windows (maximal output) Trans 277 (set A) 4.72 volts Trans 485 (set B) 4.59 Trans 451 (never-used) 4.76 Cleaning windows several times with ETOH produced the same voltages as above. Aug 10: Calibrated trans. 87 from UCSB on benchtop Trans. 87 4.42 volts Aug 11: Set software in all 4 seacats: synch clocks to GMT ca. 15 sec accuracy sample interval 600 sec (si 600) external voltages 2 (sv2) voltage delay 15000 msec (vd11250) Tested that new seacats cause fluorom to flash, and that occluding fluorom window causes fluorom output to go up as seen by seacat.
