from the NPEO 2002 Deployment
9 - Jim Johnson and Dean Stewart arrive in Resolute with the
charter C-130 Hercules carrying the container with scientific
equipment that had earlier been trucked to Yellowknife.
10 - Knut Aagaard arrives in Resolute via Ottawa. Testing
of instruments for the new mooring.
14 - Jamie and Andy phoned from Resolute. Knut and Jim flew in the
Twin Otter to Eureka Sunday, but a subsequent attempt by the Twin to
establish a fuel cache north of Alert did not work out because of weather.
The helicopter arrived in Resolute via Cambridge Bay. Weather permitting,
Jamie will take the helicopter to Eureka Monday. Andy and Dean are in
Resolute awaiting the rest of the team.
15 - Jamie reached Eureka from Resolute with the helicopter.
Weather north of Alert too bad for Twin Otter fuel cache attempt. Sigrid,
Tim, Mike, Paul, Eric and Roger fly commercial from home to Yellowknife.
Borneo position 88 degrees 45 minutes North and 93 degrees 08 minutes East.
16 - Update in Eureka -
Knut and Jim Johnson arrived here on Sunday on the Twin Otter.
The weather between here and the pole has been too poor to put out the fuel cache.
Jamie arrived here Monday the 15th after a beautiful but laborious helo flight up
from Resolute. We are waiting now for the weather to clear between here and the Pole.
Sigrid, Tim, Mike, Paul, Eric and Roger fly from Yellowknife to Resolute on the
charter FirstAir Hawker Siddley 748 to be used for the flights to Borneo,
joining Andy and Dean there. Twin Otter and helicopter waiting for weather
in Eureka with Knut, Jim, and Jamie.
17 - Update on the update -
The weather has improved enough for the first
flight to the fuel cache and the Twin Otter should be taking off
momentarily. There will be three such flights, and if they go off in
order, we should be able to head to Borneo (North Pole) later on Thursday.
With warmest regards,
Jamie, Knut, and Jim

Twin Otter and helo arrived at Borneo with Jamie, Knut and Jim.
Hawker Sidley 748 flight #1 via Alert with divers set to take off from
Resolute April 19.
19 - Hawker Sidley 748 at Resolute delayed because of need to avoid an Anatov
jet from Svalbard waiting on runway at Borneo. This first 748 flight
departed resolute at 10:40 a.m. local time for Borneo loaded with
mooring recover/deployment and diving equipment, and the divers: Mike
Paul and Eric. Borneo runway reported to be 1000 m with another 200 meter being
repaired. Fuel cache Argos position: 86deg 29 min N 76deg 04 min W.
Weather good everywhere this morning but forecasted to go down at
Resolute this evening. Local time at Resolute is PDT plus 2 hours.
19 - 4.45pm Friday, from Roger in Resolute
Jim and Knut have released the mooring and it is up as
planned (cf http://psc.apl.washington.edu/northpole/MooringRecovery.html)
under a suitable piece of ice. There is a twin otter strip right
at the site. The drift of the position is being monitored
from Seattle via an argos sender. Knut and Jim plan to
return to the site tomorrow to start setting up the recovery camp. The Hawker
Siddley has left Resolute carrying all 3 divers and should be
arriving at Borneo soon. The plane will return to Alert tonight,
and to Resolute tomorrow. It is planned to return to Borneo on
Sunday, with 2/3rds of the new mooring deployment and the J-CAD buoy. Weather
today was good everywhere. Expecting a blizzard in Resolute tonight. The runway
at Borneo was extended 200m today, making it a total
of 1200m in length.
21 - From Andy Heiberg in Resolute -
Second flight to Borneo in process with Tim Stanton, his gear, and rest
of Knut's equipment. Third one tomorrow (4/22/02) with Sigrid, Roger,
Takashi, Hirokatsu, and Andy.
Weather is good.
21 - From Knut Aagaard in Borneo -
Mooring has been recovered.
April 23 - Phone
call from Roger Andersen at Borneo, 11:00 a.m. PDT, 4/23/02 - Borneo
position at 1000 GMT 88 deg 32.4N, 87 deg 53.6E. The last of us
got to Borneo on Monday, 4/22: Andy, Sigrid, Takashi, Hirokatsu,
and Roger. Eric went back to Resolute 4/22/02, and is expected to
catch the Wednesday flight out of Resolute to home. Mooring work
is done. Knut, Jim, Paul and Mike will stay at the mooring camp
(approx. 40 miles from Borneo) tonight, and will catch the first
twin otter flight back to Borneo in the morning. They (Knut, Jim,
Paul and Mike) are expected to leave Borneo on the 748 flight on
Friday. The JCAD buoy will be deployed by twin otter on the Siberian
side of the Lomonosov Ridge on Wednesday, 4/24. Dean and Roger will
fly with Hirokatsu and Takashi to assist with the buoy deployment.
Jamie has spent most of day on the Helo, doing 4 CTD stations on
the Lomonosov Ridge. Sigrid and Tim are busily working on putting
in their buoy array at Borneo.
24 - Telephone call from Andy Heiberg, 10:00 a.m., PDT, 4/24/02
- The weather has turned bad and the 36 - 48 hr forecast is for
bad weather. The Hawker Siddley 748 may be able to fly out to
Borneo late on Friday with a second flight on Saturday. Knut and
his team are at Borneo, and have set up the huts they had out
at the mooring camp. Were able to backhaul the recovered mooring
on Sunday, 4 1/2 thousand pounds. Tim is just about finished with
his installation. Sigrid is continuing to work on hers. Both Tim
and Sigrid are within walking distance of Borneo. The Jamstec
JCAD buoy could not be deployed today because of the bad weather.
It may have to be installed near Borneo tomorrow (4/25).
25 - Telephone call from Andy Heiberg, 10:45 a.m. PDT, 4/25/02
- The wind is dying down. Weather is quite nice. The four extra
drums of fuel over and above what is required to get home are
being reserved. Cracks in the runway are being repaired and are
expected to be complete by Friday evening. The Hawker Siddley
748 will land on Friday and take out 7 or 8 of our 12 people.
A second Hawker flight on Saturday will take out the rest of the
folks and remaining equipment. Sigrid may stay on until Saturday.
Roger, Andy, Dean and Jamie will stay until Saturday. Jamie may
stay on until Sunday and fly out with the Twin Otter stopping
north of Alert to do a CTD station on the way. Everyone is helping
with the Jamstec buoy today. If the Hawker brings another load
of fuel out on Friday, one more Twin Otter run may take place
on Saturday for hydro surveys. Tim Stanton has completed his work.
The food is very good. A special dinner is being prepared for
26 Telephone call from Andy Heiberg, 2:15 p.m. PDT,
4/26/02 - The Hawker just took off from Borneo to Resolute with
Knut, Paul, Jim, Tim, Hirokatsu and Takashi, and all of their
equipment minus a few odd items. The runway repair took 5 hours,
and is now 1,100 m. 14 more drums of fuel were delivered. Jamie
was able to do three more stations on the Lomonosov Ridge. Jamie
will do one of the hydro surveys and deploy a buoy for the International
Arctic Buoy Program on Saturday. The JCAD buoy was installed.
Work began at 8 a.m. on 4/25 and was completed at 2 a.m., 4/26.
Sigrid completed her work. The Hawker plans to return to Borneo
on Sunday. Andy, Roger, Dean, Paul, and Sigrid will fly on the
Hawker to Resolute on Sunday. Jamie will fly out on the twin otter
via Alert to Resolute on Sunday. On Monday everyone (Andy, Roger,
Dean, Paul, Sigrid and Jamie) will fly to Yellowknife on the Hawker,
Andy, Roger, Sigrid and Jamie will fly to Seattle on Monday evening
or on Tuesday. Paul and Dean will head for Seattle on Wednesday.
Tentatively, of course.
report on the mooring recovery from Eric Boget, Sr. Field Engineer
and one of the divers, after his return to Seattle. Weather was
spectacular, 5-10 knot breeze. The hole melting went well. The
divers suited up and went in (Paul and Eric). 18 inches of snow
on top of the approximately 2m thick ice meant it was quite dark
in the water. The top float and the Upward Looking Sonar were
about 10 ft from the hole, and the divers could see the line hanging
down and could see the first instrument (3m below). The next floatation
package was some way away under the ice (100 ft say), so on the
whole it looked much like Jim's diagram. The divers attached a
line to the top float, and brought that back to the hole, and
exited. The mooring recovery went smoothly. It was a good, smooth
piece of ice, so the capstan pulled each package back to the hole
without the need for more diving. The line generally wasn't tangled,
except 50 ft stretches near the floatation. The recovery operation
started around 5 or 6pm, and completed by around 2am.
Observations from Jamie Morison back home warming
The helicopter CTD survey
of the Lomonosov Ridge region was completed on
April 26 in an efficient manner. To reach the farthest
site we had to carry 40 gallons of fuel internally in small drums.
Consequently we had to reduce the weight of the sampling gear
to a bare minimum (SBE-19 CTD, electric winch, andone car battery,
for an approx. 110lb) plus Jamie and
and helo pilot Rob Carroll. In lieu of ice drilling equipment
we carried a small ice chisel, and operated through very thin
lead ice (the helo landing on adjacent thicker ice). We developed
a sampling routine in which Jamie would cut a hole in the lead
ice and Rob would bring the winch, battery and CTD to the hole,
the cast was performed to 500m, and the equipment returned in
reverse order. This was a 35-minute routine, and with 20 minutes
flying between landings plus a few minutes of miscellaneous activity
we performed one station per hour. Rob's organization of the load
and his enthusiasm for the role of part-time hydro gofer were,
in addition to his obvious skills as a pilot, instrumental to
the success of the helo CTD survey. We ended up with 7 stations
spaced about 16 NM apart across the ridge.
27 Two hydro stations from the Twin otter were carried
out this day. Compared to the helo-CTD, these stations were at
a greater distance from Borneo (over 300 NM) and involved not
only CTD but water sampling as well. Consequently the Twin Otter
airplane was set up as aflying hydro platform. After landing a
hole is drilled just outside the cargo door and a tent is attached
to the side of the aircraft over the hole. A large aircraft heater
is started to keep the interior warm and a winch inside the plane
is used to lower special sample bottles and the CTD. Upon recovery,
water samples are drawn in cozy conditions from small bottle rack
inside the plane. With the tutelage of Kelly Falkner to go by,
Roger drew samples for nutrients, salinity, barium, 18O, and dissolved
oxygen (the trickiest). Stations were made at 85° 10.7' N,
165° 16.4'E and 86°37' N, 165°E. These are in a region
that is remote and seldom sampled, but which displayed some of
the largest changes in the 1990s, so it was good to get back there.
The completion of these stations, similar stations last year,
and indeed just about everything we do was critically dependent
on the skill of our Twin Otter pilot, Paul Rask, and his copilot
Doug Lesperance. We scientists say we want to go to position such
and such. Converting this wish into a successful landing at that
place is always a challenge, but especially so this year. In past
years, Paul and our other skilled pilots from First Air have usually
been able to find refrozen leads with smooth 1-2m ice. These make
ideal skiways (and are relatively easy to drill for watersampling).
This year it seemed as if all the first year ice had been broken
upduring the winter. For virtually every remote landing, Paul
had to search and search to find a relatively smooth strip on
a multiyear floe. His ability to do this at the site of the mooring
recovery was instrumental to its timely recovery.
Back at Borneo, the final couple of days centered on completing
the PMEL buoy installations. The JAMSTEC (Takashi Kikuchi and
Hirokatsu Uno) and Naval Post Graduate School (Tim Stanton) installations
were complex, but through Takashi's, Hiro's and Tim's diligent
effort and technical magic, they were completed earlier in the
week. Sigrid Salo with help primarily from Dean Stewart of the
PSC logistics group, installed a met buoy, two CRREL ice buoys,
two radiometer buoys and the now famous North Pole web cam. Thankfully
we found a relatively thick (3m) multiyear floe for the installations.
This puts the drifting station on much more secure ice than we
found in 2000 and 2001. However, this site was 1 km from the Borneo
camp, and without a snow machine, the buoy installers hauled almost
all the buoy equipment and tools out to the site on foot. We joked
that Sigrid and Dean were just like all the adventure tourists
that come to Borneo to hike to the Pole, except they hiked 60
times over the same km of ice. After some very long hours, they
finished and had everything up and running in time to depart on
the Sunday, April 28 final Hawker Sidley flight.
flew from Borneo on the Twin Otter, with the plan of stopping
at 85°N 70°W to repeat a CTD station from previous years.
There we suffered a small but memorable mistake/setback. We had
a particularly hardtime finding a place to land. The first year
ice was very broken, but Paul finally found a smooth patch. To
our surprise, the ice was so thick we didn't have enough drill
string to get through. (Before the flight we'd considered this
issue and concluded that anything over 3 m would be impossible
to land on. Wrong!). We took off again to look for the next available
smooth ice, but again to our surprise, we couldn't find a landing
site within the time and fuel constraints of the flight. We will
have to wait till next year to check on the 85° N site. Rest
assured, we will bring an extra drill extension and start searching
for skiways farther from the site. The rest of the flight was
relatively uneventful. After a stop and rendezvous with the helo
at Alert, wearrived at Resolute in poor weather about 15 minutes
after the Hawker Sidley 748 carrying the rest of the North Pole
