morning and have arrived at the Port of Wellington. After all the
mudslinging on deck and online, hard to believe that JP and I could
handle each others company. Quite the contrary...those that know us
enjoy our competitive nature and see the results that come of it. This
cruise has been no different. We are all quite happy with what has been
accomplished over the last several days, especially JP and I. We talked
at length about the cruise and our next steps in the science...we
haven't solved all the world's problems yet, but we are working on it!
The work completed here in New Zealand could not have been done without
an enthusiastic team of scientist and a competent and knowledgeable
captain and crew...we had the best. Thanks to all...the amount and
quality of work could not have been done without us all working as a team!
But enough of the comparisons, the fact is we had an all-star cast. During our last watch I walked around talking photos of the B watch members as they worked tirelessly doing their typical jobs. See the photos. Read related text below.

leader is particularly important at sea where the risks are large and
emotions run high. There are many different leadership styles. For
example, some can be excessively relaxed and apathetic, ignoring safety
concerns and proper work protocols, and disparaging and overly critical of
co-workers. Others can be completely the opposite and totally engaged in
and passionate about their work. Such leaders are typically mindful of
all safety guidelines, diligent in following science procedures,
respectful of and friendly with authorities and co-workers. During our
cruise, the watches have been lead by two very different styles (see
photos). The photo of Dr. Reide Corbett highlights how he takes a fairly
"hands off" approach in his leading. What you cannot see in the photo is
one of Corbett's angry tirades on watch, smashing ping pong balls
violently and cursing loudly at shipmates. Dr. J.P. Walsh, on the other
hand, is amiable, attentive and always puts safety first. The superior
performance and greater camaraderie of the "Dream Team" (B Watch) speaks
loudly to the importance of leadership.
continues. The A-Team finished up the sampling this morning at 5:50 AM
at a site just off of the Mahia Peninsula. By the looks of some of the
pictures taken prior to our shift, it looks like the B-Team continued to
have a good time. I think their group picture sort of describes the way
they got their work done as well...good thing the A-Team was there to
pick up the slack, eh JP (the B-Team R-L: JP, Alan Orpin, Victoria
Rosin, Julene Marr, Bella Duncan, Julia Moriarty (low), April Brown
(high), and Dick Sternberg). At the B-Team's last station, JP and Alan
were greeted to a pants full of mud...gotta love fun at sea. Although
we are done collecting samples (no more mud), there is still plenty to
do. Everything needs to be broken down, washed with freshwater (see the
wash-up crew on deck), and packed. That said, we have about a 20 hour
steam to our final destination , Wellington, so there is some time for
recreation...FINALLY! Sid and I led the Pirates to victory over the
Huskies in a mean game of Ping Pong...although to be fair it was best 2
of 3. We are finishing up some lab experiments and making sure all of
the gear is ready to be stored.
It's a good day to be at sea!
We have continued to collect CTD data, water column samples, and cores from the sea bottom. JP, Alan, and the day shift also collected some seismic data in Poverty Canyon the night before last. Julia and Joey have been working non-stop on the erodibility measurements from cores collected from a variety of sites across the shelf and slope…this will provide a unique dataset on the spatial variability of this important process (erosion/resuspension).
With all the work that is getting done, it is hard to believe we have still found time to enjoy some free time as well. We have started a make shift ping pong tournament (JP is pretty much ruling…you know that is driving me crazy), a few people jumped in the hot tub, and others have found an interest in the mini-series "Weeds" (the ship has a huge library of DVDs). So everyone finds their own way to wind down after their 12 hour shift…
The weather has really cleared up over the last few days. The sunrises have been spectacular…really make you appreciate being at sea. The seas laid down and we even put the rescue boat in the water yesterday to grab some photos o

is, but I know we've got just 2 shifts left for each watch. The weather
has become very cooperative; the gentle rocking of the vessel reminds us
that we are at sea, but is not much of a hindrance to our productivity.
We continue to CTD and core across, along, and around the Poverty Bay
margin. Some of you might be wondering what the heck a CTD is. Briefly,
this instrument measures the Conductivity (salinity), Temperature and
Depth of the water, along with some other parameters, such as dissolved
oxygen, light transmission (related to turbidity) and flouresnce (related
chlorophyll), depending on the system. We deploy this instrument over the
side of the ship and lower it to the bottom. During the profile we can
watch the data on a computer display. The CTD is also connected to a
water sampling system which allows us to "fire" a water bottle at a given
depth and collect a water sample. We typically do this so we can measure
the amount of turbidity in the water at specific depths to compare with
the instrument-measured data. That's probably enough detail. Attached are
a couple of related pics: one of Kristen and Caroline taking water from
the CTD's Niskin bottles. Two of Reide directing a CTD deployment
(including one taken from a small boat). Also, you can see a close-up pic
of the Poverty Bay coastline as well as an image of the multicore meeting
the Waipaoa River Mouth.
At this point, we have completed over 50 stations and have deployed and
recovered equipment over 100 times. There have been a few hiccups,
including a couple lost tagline poles and a CTD brushing of the bottom,
and few problems continue to pose challenges including a burned out
erosion chamber motor and a struggling x-ray system. But all in all,
things are going well. After completing a long trancsect of CTDs from
from the river mouth to the outer shelf, we ran a short survey over
Lachlan Canyon. This provided some valuable additional data on the
sediment cover of this region, adding to our existing dataset from
previous cruises to understand sediment thickness and character. Of
course, we still have more mud to collect. I better get down to the deck
because my watch starts in 10 minutes!

There has been a lot going on today. In the last hour I've been working on fixing a pump and a filtering system for the Erosion Chamber. This is a typical type of cruise problem. Things always decide to stop working, but now it looks like we're back in business.
Overall, it's been a pretty successful day, but we've certainly had our problems. We got two tripods deployed and have CTDed and cored at a few sites now. We had quite a bit of trouble with the multicore earlier, but after many failed attempts, we eventually for the issue (tigger was not locking in place) and got it repaired. Hopefully we can have a productive day tomorrow.
I need to hit the hay. G'Day, J.P.
Sorry, I'll try to get some pics up in the morning.

For purposes of evenly distributing workload, two 12h shifts have been set up: a midnight-to-noon shift and a second noon-to-midnight shift; there are eight scientific crew per each shift. Once we get to the first station, the first task will be sending off the rosette with the Niskin bottles and collecting conductivity-temperature-depth (CTD) data. After that, we will deploy the multi corer and retrieve some cores to get an idea of the seabed. If all looks good, we will deploy the first tripod. Getting everything going at the first station is always a challenge but we have an eager and hard-working group so we will get er done!!
