Larry, please pass on copy to Capt. Murline.
In conversations with Dave Murline, New Horizon would have to leave by 0200
on the 26th in order to arrive at 1600 on the 27th. But daylight departure
is preferred.
Conversation with Dr. Francisco Chavez this morning:
MBARI truck to arrive San Diego evening of the 16th. 17th scientific party
will be loading gear. Dr. Chavez would like to have scientific party spend
the night on board New Horizon the night of the 17th. Depart 0800 on the
18th.
Additional plan for offloading and arrival and departure from Monterey on
the 23rd and 25th of March.
Again, as pointed out in memo from the RT's most of the hydrographic
equipment will be offloaded at the intermediate stop on the 23rd of March.
The plan is to arrive into Monterey early dawn on the 23rd, offload the
hydro gear, depart dusk on the 23rd, deploy moorings, return to Monterey 25
March by 1400, offload personnel. The Pengo winch and remaining gear will
be offloaded at the CG Pier on the 25th if time permits, if not will be
left on board to return to San Diego and offloaded.
Dr. Chavez will have New Horizon ready for departure at 1700-1800 (before
sunset) on the 25th.

Dr Chavez,
The following is a rough outline of how I currently understand the cruise.
There are some questions I have that may be answered in your meeting this
afternoon.
Lynne Butler
Chavez' concerns:
How much can ship's crane lift?
The crane will lift 3000 lbs.
Loading in San Diego:
all Hydrograhic eqpt, w/ scientists' assistance
CTD
Nets
Vertical
Bongo
optical plankton counter
Tracemetal towfish
van #7, 01 deck
Extra SIO (Seamac) winch with 700 feet .322" wire - for OPC, Bongo
?Pengo winch - for all 3 moorings?
mooring anchors
Loading in Monterey, Coast Guard pier, March 23:
Dr. Chavez will know by 1/29/98 about pier capacity and permission to use
M3 buoy
S2 & S3: 2 large spheres each with an ADCP, 1100 lbs ea
Leave at sea
mooring anchors
M3 buoy
S2 mooring
S3 mooring
Offload in Monterey, Coast Guard pier:
everything belonging to scientists
all Hydrograhic eqpt
Offload in San Diego:
van #7, 01 deck
SIO winch with .322" wire
Extra SIO (Seamac) winch with .322" wire
Pengo winch
Operations, Equipment
LEG 1
HYDROGRAPHIC
CTD
Drew Gashler 408-775-1936
12 bottle, Seabird 911plus and carousel
Nets
Vertical-Which winch will be used? Seamac?
Bongo-How much line out?
Russ Hopcroft 408-775-1828
Tracemetal towfish-
Ken Johnson 408-755-8657
Towed continuously while underway, 8-14kts, 3-4 m below surface, 10-15 ft
away from side of ship, 40-100 lbs, adjustable dymnamic depression fins to
make it tow down and away from ship. 3-4 sq ft max diving planes. It will
be brought in daily to check its condition. While on station it will be
brought up to the surface and the pump turned off. Stainless steel w/teflon
pump. tubing attachment for water sampling. Pump uses compressed air - not
a very high cfm. ?Will compressed air be supplied by ship or will
scientists bring a compressor? ?attachment for compressed air pump? 5/8"
braided dacron line around capstan. through a 18" diameter block. ?Do all
cables/line go through the block or only the dacron line? Ken Johnson will
be responsible for the attachments / termination.
1/28/98 There is active discussion about the mounting of a device to get
the towfish at least 10 ft away from the side of the ship. The current idea
includes a 20 ft box beam with a plate of 4 padeyes at the outboard end and
secured to the bulwark and an inboard stand on the main deck. This position
will provide good access to the capstan. At least two stays (forward and
upward) will strengthen the beam. Ken Johnson has suggested the beam be
tilted upward to prevent dipping as the ship rolls.
1/30/98 towing system is still in discussion
LEG 2
Hydrography if interesting features discovered.
Mooring M3 surface
Tom Tengdin 408-656-1920 will not be on cruise

through A-frame
Buoy = 3000 lbs, 1.5 m diameter
thermistors every 30 m 0-350 m wire out
current meters?

?How much space will hydrographic eqpt take up?
6000 m thin cable
anchors 2ea
Need trawl winch to lift anchors into the water
rode
box - 4 sq ft with shackles, pearrings, deck gear...tied to deck outside
Marla will supply snatch blocks, chain grabs...She has no large wide
mouth blocks that will accept 5/8" pearrings, etc.
SIO will supply large wide mouth block

Wire for S3 & M3 on pengo reel. These will be deployed first.
?Wire for all 3 moorings may fit on Pengo spool?
?Who will deploy these moorings?
2 resident technicians, and:
per Marla: 2-3 people from NPS, 5-6 people from MBARI
She will have 2 reels of wire besides what will be on Pengo. Marla will
bring payout cart (200-300 lbs, 4-5 sq ft, 3-4 ft ht) to wrap wire on
Pengo.
Two spools of wire for the Pengo winch?
If so:
Where change spools?
