Expedition 390 ALO Tech Report

Expedition Info

Embarked April 9th  and disembarked June 9th. Due to a mechanical failure of the drawworks break, the ship tied up on May 31st in Cape Town and began port call activities.  Both port calls were Cape Town, South Africa.  Scientists began disembarking June 3rd/4th.

We sailed one program aide in thin section (Aidan Leetz) and were missing a chemistry technician. Chieh filled in as the second chemistry technician.  Tracer pumps were used throughout the expedition with approximately 800 ml used for 24 hours.

Notes

• The 390C and 395E cores were flagged as 'legacy' data at the start of the expedition.  This prevented edits to the sections (i.e. lengths when binning the hard rock sections).  The developers removed the legacy flag and will merge the data with shore at EOX.  The tests are also flagged as legacy, which prevents the user from canceling or modifying data from 390C/395E.  A programmer had to assist when previous data needed to be removed.

• Nitrogen generator filters were changed.  One had a lot of black gunk when removed, but the final filter was much cleaner than the first filters.

• Check with the other SIEM crew, but we were given the okay to start dumping waste oil into the waste oil tank ourselves again. (starboard main deck pipe near entrance to mud pump room)

• Turned on and used large incubator in TBulk for overflow chem samples.

• Catwalk drain valve not closing properly. Must open/close using large white wheel valve to flush the catwalk drain until SIEM can fix.

• Supplies specific to Exp 393 were placed in an empty drawer (30D-5)  in UTS.  These include MB0087, MB0086, and cryovials that arrived for Labonte in the 393 air freight.  The anaeropacks MB0051 are in boxes in HRS.  LS5337 (black filter paper) is in 28D-2 with similar items.

• Most of the Air Freight that arrived early in portcall was unpacked.  The Packing Slips were collected and notes were included on each to indicate where the items are now.

• Spare parts for the Zero Lift are in the logistics drawers in Upper Tween

• Towed Magnetometer was lost during retrieval.

COVID Protocol

Most of the sailing staff arrived to the hotel in Cape Town on April 2nd. We quarantined at the hotel until crew change on April 9. 2 PCR tests were done for all on-signers in the hotel during quarantine.  Four staff members boarded late due to illness/delayed flights/passport issues.  Crossovers with the onboard staff were conducted at the hotel via ZOOM. Everyone was able to board after the hotel quarantine. For the first seven days onboard we had a daily antigen test. From days eight to fourteen we had an antigen test every other day. No COVID cases while onboard.  SIEM requested daily antigen testing starting June 3rd until our final tests prior to flying.

Tracer Pumps

• RigWatch was unable to communicate with the pumps at the start of the expedition. The issue was tracked to an incorrect IP address that was only identified by connecting a laptop to the black box in the tracer pump box. After the communication issue was solved, the drillers were able to control the tracer pumps with no issue.

• On the first full day of pumping tracer, the tracer level stopped decreasing.  We checked and changed various tubing.  After approximately 12 hours, we disconnected the stainless pipe connecting to the mud pump line of pump 2 and reconnected it and shortly after it started pulling tracer from the bottle again.

• TracerWatch works best on the Chrome browser.

• Pumps were put into standby mode at the end of operations and everything was cleaned up. There is a bottle of methanol, isopropyl, and two bottles of PFMD left in the pump box.

• Spare parts for remaking the tubing connections were requisitioned and arrived in the 393 AF.  These parts were put into the PFT drawer in the UTS.

Requisitioned Items:

• Air line lubricator replacement/spare for PhysProps.  Arrived in 393 AF and is now in PPTRKF5.

• Two spin mops.  They were not added to the AMS inventory yet.

• Cargo net with 2" mesh to put over core racks in rough seas.

Shipping

Shipment issues were noted and  a report was sent in to shore after port call.  Multiple items did not make the April port call and were delivered on May 31st.  A cold shipment from College Station is still pending with chemicals.

Items include:

• Acetone (Unpacked into BFLM)

• Isopropanol (Unpacked into BFLM)

• DEWALT 20-Volt Max 2-Pack 2 Amp-Hour Lithium Power Tool Battery Adapter Kit (Charger Included) (Items delivered to ET shop)

• World Courier Refrigerated Shipment from College Station (Items placed in FMBIO Cold Room)

• World Courier Frozen Shipment from College Station (Items placed in -20 in HRS)

Items that were not sent from IODP prior to 390:

• L-Homopropargylglycine (HPG), 1000 mg, 1067-1000. For Exp390/393 Scientists. (Will be coming to Cape Town in a cold shipment)

• L-Leucine 7-amido-4-methylcoumarin hydrochloride, 1 g, 50-171-5257. For Exp390 Scientists.  (Will be coming to Cape Town in a cold shipment)

On coming AF arrived May 31st.  Remainder of freight scheduled for June 7th.

World Courier 

We had a large number of World Courier shipments from 390.  World Courier no longer uses blue ice in their packages of refrigerated and are unable to refill in transit.  We must order refrigerated containers from WC.  Exp. 390 used the GTC56L and custom technician made cardboard boxes for samples to ship scientist vials/samples.  Igloo coolers with a vent drilled in the back were used for all the frozen shipments.

AMS/inventory/store rooms

• Ship store was migrated to credit card system.  See Credit Card Sale Instructions and IODPS Credit Card Sales SOP on the ALO notebook page. A store receipt was generated to automate the receipt making process. 

  • We need to keep all the credit card paper receipts and scan them in to send to Mia at the end of the expedition.  They do not need to be attached with each pdf receipt as long as you fill in the credit card reference number on the pdf receipt.  We created a master pdf of all the credit card receipts from the machine and sent it to Mia at the end of the expedition.

• Store Items for 393 arrived in Air Freight on May 31st and were unpacked into the drawers.  Note that there were some quantity discrepancies that need to be taken care of after items are received. 

• New Masks were added to the inventory (SF5062) and were put into plastic boxes in the store room.  They are in S1 area.  They have been rubber banded into groups of 10.

Discussion/important information for upcoming expedition

• Completed disposal forms in AMS for Pipette N2115.008 and N2115.015

•  

  • Make sure technicians don't dispose of any property items without going through the proper steps (pipettors must have a disposal form completed prior to disposal)

• Please leave at least 4 empty plastic kboxes on board for tie-up if possible.  SIEM needs to repair the doors to BHAZ and BFLAM and we will need to empty the store rooms during the work.

• The water pipe inside the super saw was replaced during the transit back to Cape Town after we noticed a hole had been worn through the pipe.  

• Core cutter 51270 was repaired and 51260 was unable to be repaired.  We found the drawings (from Eric Schulte) for the core cutters.  We need to discuss which core cutters we want to have made in the future.

• If the seas get rough and the ship begins rolling more side to side, watch the Archive rack.  We had dtubes (with core) sliding out when the seas were not all that heavy.  A cargo net was requisitioned to hopefully secure the dtubes better in heavy seas.

Samples and Equipment left onboard

-Working half sediment sections and shipboard sample residues in the reefer. Send to BCR at the end of 393.  During the expedition we kept the working half sediment sections separated from the rock sections.  The curator along with EPM were to make the decision on what was 'sediment', especially at the transition zones between rock and sediment.  We marked the boxes with a "KEEP ON SHIP" sticker to help us easily identify which boxes of core to keep separate.  When we reboxed the 395E and 390C boxes, they were assigned new box numbers and new boxes were made because the old ones were too damaged.

-Jason Sylvan's plate reader and oxygen system is in the chemistry lab and FMBIO.  The plate reader was shipped out in T39002S/054318/17892/043852 and the shipping crate is in upper tween staging area.  The rest of his equipment was hand carried.  It can either be shipped back or Ying Wee can carry the items home.  

*Please note there are samples for REESE and REECE left on board.
