11/19: Atlantis arrived 1 day early to San Diego (19th instead of the 20th) will use the extra day for demobe.
11/16: 1 day early departure d/t berth availability
11/8: Departed for Guaymas on the 7th instead of the 8th to make up for transit mistake (7 days were allocated when 8 were needed).
11/1: 1 day later arrival into Puntarenas (Oct 14th), 1 day added to NSF-OCE-BIO" on the transit and 1 day removed from the same on the load.
10/8: Departing San Juan 1 day later d/t thruster issue. ETA Costa Rica holding. (In port charged 1 more day to BIO, removed 1 transit day from BIO (breakeven).
8/8: "Alvin/LARS NAVSEA Survey has been officially
rescheduled from July 2018 to the week of 07 January 2019 (in the
shipyard)."
5/15: Take 1 of Cordes' mobe days & Sentry's eng dive days (to MGG) over to San Juan for 2 additional PREmobe days for PAC cruises.

Hopefully will get to San Diego in time for the Outreach event.
3/22: Gregg cruise awarded 1 more day for Alvin dives.
1/12: Return from OOI AB Jan 20th (not the 21st)

9/5: Shift Koppers 3 days to the left for the OOI AB -3 days.

7/17: Demobe Lang in PR to save on deadhead transit (3 days overall savings)
6/30: Moved Lang to the left 1 week to get Jason 2 weeks to transit from Bermuda to WA (Tivey on Ride)
5/31: Orcutt w/ Jason on Ride
4/6: Need to add time at WHOI for ABS and in Astoria for Navsea???
4/3: End Hutchins in Barbados
2/21: June NAVSEA Ext. Cert. Survey (5 days) WHOI
2/20: Hutchin's IN/ Saito & Hodgekiss OUT (Armstrong)
1/31: Corrected Johns voyage from 2015-18
-Cordes wants his 2017 cruise 14 months before the 2018 cruise.
12/29: S. Lang Cayman DECLINED, Karson & Wanless "W" |

| Repeating Cruise: |
No |
Dates To Avoid: |
The rainy/storm season should be avoided (May to September; August and Sept. are particularly problematic). Hurricane season in the Gulf of California is late summer and early fall; most hurricanes are falling into August/September/early October. The currently chosen dates, Nov. 15-29 [already in the 2018 ship schedule for Atlantis] are fine. |

| Justification/Comments: |
We need the Alvin/Atlantis to accomplish our research goals. Given the number of sediment cores we need to retrieve, and the in-situ instrumentation that we have to deploy, ALVIN is the best platform for our program. The target area is already well mapped [most recently with SENTRY, Dec. 2016], allowing efficient navigation and sampling at dive targets. ROVs are unsuitable due to much more limited sampling and carrying capacity.
AUV Sentry was added to the cruise in February 2018, to map hydrothermal plumes in fine 3D resolution around the previously mapped hydrothermal sites. |

| Requested Start Port: |
Guaymas, Mexico |
| Intermediate Port(s): |
None, |
| Requested End Port: |
Guaymas, Mexico |
| Port Comments: |
The current plan by WHOI for cruise AT42-05 is to mobilize in Guaymas, and to demobilize in Manzanillo.
Regardless of the start port, it is imperative that science equipment and most science samples be loaded and unloaded in a US port, to avoid a repeat of the 2016 Mexican shipping disaster. At the time of updating this shiptime request [March 8, 2018], WHOI plans to load chemicals at WHOI in September, and lab gear in San Juan, Puerto Rico in October; samples and gear are offloaded post-cruise in San Diego. |

|
| Foreign Clearance Comments: |
Foreign Clearance Comments: Mexican clearance will be required, also for collecting microbial mat and sediment specimens. One or two Mexican observers/scientists will be members of the cruise party. On the Dec. 2016 cruise, the necessary Mexican clearance could be obtained at last but it did require more time than the previous expeditions did. |

|
| Instrumentation Requested: |
Dynamic Positioning
Multibeam
Radioisotope use - briefly describe
|
| Instrumentation Comments: |
We will be doing radioisotope tracer work using weak beta emitters [tritium, C14, S33] in the isotope van - as we have done many times in the past on board the Atlantis. We may also use non-radioactive isotopes [C13, N15]. |
| Ancil Facilities Requested: |
Sentry
Alvin
Radioisotope Lab Van
|
| Ancil Facility Comments: |
SENTRY is requested, and has been approved by NSF, for high-resolution mapping of hydrothermal plumes around the previously mapped hydrothermal targets in Guaymas Basin. Since Sentry is already placed on RV Atlantis before and after the Guaymas cruise, no additional shipping is required; Sentry stays where it is and it put to good use during the Guaymas Basin cruise. |
