| Summary: | CalCOFI 1907BH sailed on RV Bold Horizon at 0800PDT 11 Jul 2019 from 10th Ave Marine Terminal San Diego. 70 of 75 science stations were completed. CTD casts, secchi disk casts, and various net tows were completed at each science station. Underway visual observations of marine mammals and avifauna were conducted while under transit and coupled with sonobuoy deployments at each station. Other underway science included continuous pCO2/pH and meteorological measurements. Unfortunately, approximately 12 hours were lost early in the cruise due to satellite communications malfunction. The ship diverted from the standard CalCOFI cruise track after 93.3 45.0 north to San Clemente Island to affect repairs and resumed work at 93.3 50.0. |

II.B.1. Underway Operations
II.B.1.a. Thermosalinograph sampling - Science will provide and maintain a thermosalinograph (TSG), which is calibrated and in working order, for continuous measurement of surface water temperature and salinity.
II.B.1.b. Acoustics: NA
II.B.1.c. Acoustic hydrophone: NA. Upon approaching a station, two sonobuoys will be deployed one nautical mile prior to stopping for station work.
II.B.1.d. Expendable wave measuring drifter. NA
II.B.2. Station Operations
Each standard station will include the following:
II.B.2.a. CTD/Rosette consisting of 24 10-liter hydrographic bottles will be lowered to approximately 515 meters (depth permitting) at each station to measure physical parameters and collect water at discrete depths for analysis of: salinity, nutrients, oxygen, chlorophyll, etc.
II.B.2.b. CalBOBL (CalCOFI Bongo Oblique): standard oblique plankton tow with 300 meters of wire out, depth permitting, using paired 505 µm mesh nets with 71 cm diameter openings. The technical requirements for this tow are: Descent wire rate of 50 meters per minute and an ascent wire rate of 20 meters per minute. All tows with ascending wire angles lower than 38° or higher than 51° in the final 100 meters of wire will be repeated. Additionally, a 45° wire angle should be closely maintained during the ascent and descent of the net frame. The port side sample will be preserved in buffered ethanol at every station.
II.B.2.c. Manta net (neuston) tow: using a 505 µm mesh net on a frame with a mouth area of 0.1333 m². Tows are 15 minutes in duration at towing speed of approximately 1.5 - 2.0 knots. Wire angles should be kept between 15° and 25°.
II.B.2.d. Pairovet net: will be fished from 70 meters to the surface (depth permitting) using paired 25 cm diameter 150 µm mesh nets at all stations out to and including station 70.0. The technical requirements for Pairovet tows are: Descent rate of 70 meters per minute, a terminal depth time of 10 seconds and an ascent rate of 70 meters per minute. All tows with wire angles exceeding 15° during the ascent will be repeated.
II.B.2.e. A PRPOOS (Planktonic Rate Processes in Oligotrophic Ocean Systems) net will be taken on specific stations on line 90.0, 86.7, 83.3, and 80.0. These stations are occupied as part of the LTER (Long Term Ecological Research) project. The mesh of the PRPOOS net is 202 µm and the tow is a vertical cast up from 210 meters. The technical requirements for the PRPOOS tows are: Decent rate of 40 meters per minute, a terminal depth time of 20 seconds and an ascent rate of 50 meters per minute.
II.B.2.f. Primary productivity: at about 1100 hours on each day a primary productivity CTD cast consisting of six 10-liter hydrographic bottles (mounted on CTD frame) will be carried out. The cast arrangement will be determined by a Secchi disc observation. This cast will be in conjunction with an already scheduled station. The purpose of the cast is to collect water from six discrete depths for daily in situ productivity experiments. Measurements of extracted chlorophyll and phaeophytin will be obtained with a fluorometer. Primary production will be measured as C14 uptake in a six hour in situ incubation. Nutrients will be measured with an auto-analyzer. All radioisotope work areas will be given a wipe test before the departure of the SIO technical staff.

VI. Disposition of Data and Reports
A. Data Responsibilities
The Chief Scientist will receive all original data related to the project. The Chief Scientist will in turn furnish the Captain with a complete inventory listing of all data gathered by the scientific party, detailing types of operations and quantities of data prior to departing the ship if requested. All data gathered by the vessel's personnel that are desired by the Chief Scientist will be released to him, including supplementary data specimens and photos gathered by the scientific crew.
B. Pre and Post Project Meeting
Prior to departure, the Chief Scientist will conduct a meeting of the scientific party to train them in sample collection and inform them of project objectives. Some vessel protocols, e.g., meals, watches, etiquette, etc. will be presented by the ship.
VII. Miscellaneous
A. Meals and Berthing
The ship will provide meals for the scientists listed above. Meals will be served 3 times daily beginning one hour before scheduled departure, extending throughout the project, and ending two hours after the termination of the project. Since the watch schedule is split between day and night, the night watch may often miss daytime meals and will require adequate food and beverages (for example a variety of sandwich items, cheeses, fruit, milk, juices) during what are not typically meal hours. Special dietary requirements for scientific participants will be made available to the ship’s command at least seven days prior to the survey.
Berthing requirements, including number and gender of the scientific party, will be provided to the ship by the Chief Scientist. The Chief Scientist will work on a detailed berthing plan to accommodate the gender mix of the scientific party taking into consideration the current make-up of the ship’s complement. The Chief Scientist is responsible for ensuring the scientific berthing spaces are left in the condition in which they were received; for stripping bedding and linen return; and for the return of any room keys which were issued. The Chief Scientist is also responsible for the cleanliness of the laboratory spaces and the storage areas utilized by the scientific party, both during the project and at its conclusion prior to departing the ship.
B. Shipboard Safety
Wearing open-toed footwear or shoes that do not completely enclose the foot (such as sandals or clogs) outside of private berthing areas is not permitted. Steel-toed shoes are required to participate in any work dealing with suspended loads, including CTD deployments and recovery. The ship does not provide steel-toed boots. Hard hats are also required when working with suspended loads. Work vests are required when working near open railings and during small boat launch and recovery operations. Hard hats and work vests will be provided by the ship when required.
