1.2  Cruise Summary Information

Summary

In the evening of Thursday 24 September, RV Pelagia left Scheveningen and set 
course to the position in the Irminger Sea where the LOCO2 profiling mooring 
has been be recovered and re-deployed. After leaving port the underway 
recording system for navigational, meteorological, ADCP, and sea surface data 
was activated. After the mooring activities a CTD survey was carried out 
along the AR7E section between Greenland and Ireland, and along an additional 
small section near Ireland. On October 13 RV Pelagia entered the port of 
Galway.

Cruise Track

The cruise was carried out in the northern North Atlantic Ocean. The cruise
track is shown in figure 1


Figure 1: Cruise track of Pelagia cruise 64PE312, from Scheveningen 
          (Netherlands) to Galway (Ireland).


Mooring Deployments

Mooring LOCO2-6 was recovered after which mooring LOCO2-7 was deployed on 
October 2. The mooring operations took place during daytime. The position of 
the deployment of LOCO2-7 is: 59°12.21'N, 39°30.49'W (cross in Figure 2), the 
deployment time is 17:44 UTC. During the last 10 minutes before deployment

Pelagia has followed a course over ground in the direction of 314° relative 
to North. Both LOCO2-6 and 2-7 are profiling moorings, fitted with a 
McLane/FSI CTD profiler, two RDI Long Ranger ADCPs and an SBE Microcat CTD. 
They were deployed at a depth of about 3000 m at the foot of the East 
Greenland slope, approximately in the centre of the Irminger Gyre. See also 
Appendix B.

Number of Hydrographic Stations

A total of 42 CTD casts were performed along the former WOCE AR7E section, 
and 6 stations along the additional section across the Irish continental 
slope. The location of these casts is shown in figure 2. The mutual station 
distance is about 30 nautical miles, while over steep topography that 
distance was reduced to about 15 miles. Due to adverse weather conditions a 
planned CTD station 30 miles east of the Hatton Bank had to be cancelled. 
Further information on the time, location can be found in the Cruise Summary 
File (Appendix A).

1.4  Scientific Programme and Methods

The dual goal of the research carried out during the cruise was to establish 
the hydrography along a zonal section between Greenland and Ireland to allow 
the study of inter-annual hydrographic variability and to service an 
instrumented mooring in the Irminger Sea, both as part of the EU THOR 
programme, and as an extension of the CAMP monitoring programme of NIOZ.

The zonal section is the former A1E/AR7E section of the WOCE Hydrographic 
Programme, which has been surveyed near-annually since 1990. The re-survey of 
this section is carried out in order to determine climate related inter-
annual changes of the hydrographic structure in the North Atlantic Ocean.

The CTD frame was fitted with weights in order to secure a fast enough 
falling rate. This package was lowered with a velocity of about 1 m/s, except 
in the lowest 100 m where the veering velocity was reduced. Measurements 
during the down-cast went on to within 12 m from the bottom, until the bottom 
switch indicated the proximity of the bottom. During the up-cast a few 
temperature samples where taken with the SBE35 reference thermometer at 
prescribed depths, when the CTD winch was stopped.

The mooring which was recovered (LOCO2-6) and re-deployed (LOCO2-7) was 
funded as part of the Dutch Long-term Ocean Climate Observations programme 
(LOCO). This programme aims at the establishment of a monitoring system which 
records climate relevant oceanographic parameters at several locations in the 
world ocean. The moorings contain a profiling CTD which will record on a 
daily basis profiles of temperature and salinity between ~2400 and 160 m 
depth (McLane profiler). Additionally ADCPs will record the velocity profiles 
in the upper and lower 600 m. Mooring LOCO2-7 is the 7-th of a series of 
moorings, each deployed for one year in the centre of the Irminger gyre.

On board data processing of the ACDP data was carried out. From the profiler 
data preliminary ASCII files with temperature and density as functions of the 
pressure were produced. Not enough time was available for complete data 
processing, which will be carried out back at NIOZ. Because of a 
misunderstanding the Microcat was redeployed before the data were retrieved. 
These data will become available only when the mooring is recovered in 2010.

In support of the CTD observations the sea surface temperature and salinity 
were recorded continuously as well as several meteorological parameters. Also 
the currents in the upper 600 m were recorded with the vessel mounted 
acoustic Doppler current profiler (VMADCP).

2  Underway Measurements

2.1  Navigation

A differential GPS receiver was used for the determination of the position. 
The data from the Sercel GPS receiver and the gyro compass were recorded 
every ten seconds in the underway data logging system. An additional Seapath 
dual antenna GPS receiver also determined the ship’s heading. Data processing 
will be carried out back at NIOZ.

2.2  Echo Sounding

The 3.5 kHz echo sounder was used on board to determine the water depth.
The uncorrected depths from this echo sounder were recorded in the underway 
data logging system.


2.3  Thermo-Salinograph Measurements

The Sea Surface Temperature and Salinity were measured continuously with
the SBE Seacat thermo-salinograph system with the water intake at a depth of
about 3 m. These sensors will be calibrated by comparison with the CTD-cast 
at 3 m.


2.4  Meteorological data

Air temperature and humidity, relative wind velocity and direction as well as
air pressure and solar radiation were measured and recorded by the underway
logging system. The connection with the solarimeter appeared to be defect.
Therefor the solar radiation data are missing from the meteorological 
records.


2.5  ADCP measurements

The 75 kHz ADCP mounted under the Pelagia has been used to collect current 
data from the Irish continental break onwards. The final processing of the 
data will take place back at Texel. The VMADCP data were collected with a 
dedicated service computer, together with the appropriate navigational data. 
Daily these data were transferred to the appropriate directory of the ships 
computer network. On board the first phase of VMADCP data processing took 
place. 



3  Hydrographic measurements - Descriptions, Techniques, and Calibrations

3.1  CTD Data Collection and Processing

A recently (August 2009) calibrated SBE 9/11+ CTD, SN-0942, has been used to 
measure temperature, salinity, and turbidity profiles. The sensors mounted on 
the CTD were an SBE3 temperature sensor SN-034384, SBE4 conductivity sensor 
SN-040995, a Digiquartz pressure sensor SN-113589, and a Wetlab CStar beam 
transmission meter SN-CST-1112DR with a path length of 25 cm.

The CTD was mounted in a special rack, which did not contain water samplers. 
The sensors of the CTD were recently calibrated by the manufacturer. To 
control the temperature measurements an SBE 35 Deep Ocean Standards 
thermometer was mounted next to the temperature sensor of the CTD. Reference 
temperature samples were taken with this thermometer in deep low-gradient 
layers.

For the data collection the new Seasave software for Windows (version V 
7.18c), produced by SBE, was used. The CTD data were recorded with a 
frequency of 24 data cycles per second. After each CTD cast the data were 
copied to a hard disk of the ship's computer network, where a daily back-up 
copy was made.

The CTD data were processed with the recently obtained calibration data, 
using the Seasoft software, also produced by SBE, and reduced to 1 dbar 
average ASCII files. These were used for the preliminary analysis of the 
data. The final data processing will be completed at Royal NIOZ, Texel.


3.2 Reference temperature measurements

Mounted on the CTD-rack was a high precision SBE35 reference temperature 
sensor, which recorded the temperature on commands given by the CTD operator. 
These SBE35 temperature data will be used to control the calibration of the 
CTD temperature sensor. The preliminary difference TSBE35-TCTD amounts to -
0.002°C (±0.001°C stdev).

 
3.3 Data Management

All raw data were copied to a cruise directory on the network computer in 
different groups of sub-directories. Subsequent processed data, final 
products, documents and figures were copied to separate sub-directories 
within the cruise directory. Back ups of the network disks were made on a 
daily basis. At the end of the cruise copies of the whole cruise directory 
have been made on portable hard-disk. By help of paper measurement forms and 
computerized data inventory files all data are tracked. A final inventory of 
the mooring activities, hydrographic stations, and the available raw data 
files was made in a cruise summary file (Appendix A).

 

4 Preliminary results

4.1 The Irminger Sea 

The θ-S diagram for the CTD stations in the Irminger Sea (Figure 3) shows 
that the most saline water in this basin is observed over the Reykjanes Ridge 
(stations 15 to 17) and over the continental slope of Greenland (stations 6 
en 7).


Figure 3: θ-S diagram for the CTD stations in the Irminger Sea, from the 
          Greenland continental shelf to the top of the Reykjanes Ridge.


After the cold winter of 2008 a cold and fresh Sub-Arctic Mode Water was 
formed in the Irminger Sea with a potential temperature of about 4.5°C and a 
salinity of 34.85. During the THOR cruise from 2009 the central Irminger Sea 
was strongly salinified compared to 2008, with sub-surface salinity maxima 
from 34.93 to 35.01 near the density levels of the 2008 Mode Water.

At the levels of the Labrador Sea Water (LSW) class or vintage, formed in 
2000, the θ-S properties hardly had changed, compared to 2007. No trace was 
found yet of the Labrador Sea Water vintage, formed by deep convection in 
2008. The high-density Labrador Sea water, formed in the cold period of 1988 
to 1994 (LSW94), still visible as a deep salinity minimum in the Irminger Sea 
in 2007, could not be recognized in 2009 from the q-S properties.

The near-bottom temperatures and salinities in the homogeneous near bottom 
layers in the western half of the Irminger Sea reflect that the temperature 
and salinity of the Denmark Strait Overflow Water is colder and less saline 
than observed during hydrographic surveys in 2007 and 2008.


Figure 4: Profiles of potential temperature, salinity, and potential density 
          anomaly from the CTD casts in the Irminger Sea.

 
The hydrographic profiles from the Irminger Sea (Figure 4) show a doming of 
the isopycnals in the cyclonic Irminger gyre (part of the sub-arctic gyre), 
with stations 8 to 10 in the centre of the gyre. These stations also show the 
lowest sub-surface salinities and temperatures. The density distribution in 
the upper 1000 m agrees with a southward baroclinic geostrophic transport 
west of station 8 relative to 1000 dbar of about 1.5 Sv (1 Sv = 106 m3/s), 
and a northward transport between station 8 and station 17 over the Reykjanes 
Ridge of about 4.4 Sv.

The deep density differences between neighbouring CTD-stations over the 
continental slope of Greenland agree with a strong bottom intensified 
southward flow of Denmark Strait Overflow Water (DSOW) along the Greenlandic 
slope. The deep density gradient between stations 15 and 17 suggest a 
northward baroclinic flow of the saline Icelandic Slope Water en the upper 
parts of the North East Atlantic Deep Water along the Reykjanes ridge.


4.2  The Iceland Basin

In the upper layers of the Iceland Basin the main difference with the 2007 
survey is a less strong gradient in the frontal zone of the North Atlantic 
Current in 2009. The range of the near surface salinity in the Iceland Basin 
is similar in both years.

 
Figure 5: θ-S diagram for the CTD stations in the Iceland Basin between the 
          Reykjanes Ridge and the Hatton Bank.


The θ-S diagram and the hydrographic profiles for the 2009 survey of the 
Iceland Basin (Figures 5 and 6) again shows a thick layer with a salinity 
minimum. This is a combination of the LSW vintages formed in 1988 to 1994 and 
in 2004. The latter occupied the deeper part of the basin and is absent west 
of 27°W. the salinity value in the salinity minimum connected with the 
LSW2000 vintage has increased with over 0.01 since 2007. the salinity increase 
of the LSW94 class since 2007 is smaller, ~0.007. The relative salinity 
maximum, connected with the intermediate saline layer between both LSW cores 
increased in salinity value, but decreased in amplitude, compare to the 
salinities of both LSW cores.

 
Figure 6: Profiles of potential temperature, salinity, and potential density 
          anomaly from the CTD casts in the Iceland Basin.

 
As in 2007 a near bottom layer of Iceland-Scotland Overflow (ISOW) water can 
be recognized as the coldest water over most of the western slope in the 
Iceland Basin. The salinity and potential temperature of this water type in 
2009 is warmer and more saline than in 2007. ISOW shows in the hydrographic 
profiles as a thick layer with near homogeneous, relatively high salinity. 
The relatively high potential density in these ISOW layers agrees with a 
baroclinic bottom intensified southward flow of ISOW over the western slope 
of the Iceland Basin. East of the deepest point in the Iceland Basin, The 
Maury Channel, the bottom density is also relatively high compared to the 
same levels at the station in the Maury Channel, indicative for a bottom 
intensified northward baroclinic flow over the slope of the Hatton Bank. The 
usual near-bottom salinity minimum due to the presence of Lower Deep Water in 
this northward flow is absent in the 2009 data.

 

4.3  The Rockall Trough

Compared to the other Irminger and Iceland Basins, the Rockall Trough does 
show less intrusive structures (Figure 7). Overall the q-S structure in 2009 
hardly differs from the structure observed in 2007. The salinity minimum near 
q = 3.2°C, connected with the presence of a core of LSW, decreased in 
salinity with only about 0.003 over the last 2 years.

 
Figure 7: θ-S diagram for the CTD stations in Rockall Trough.

 
Below the salinity minimum of the LSW core, a salinity maximum of slightly 
over 34.93 is observed at a depth of about 2700 m, related to the aged ISOW. 
Near the bottom near 2900 m on the additional CTD section a salinity minimum 
of S = 34.92 is observed, related to the presence of the upper layers of 
Lower Deep Water (LDW), extending from the Porcupine Abyssal Plain into the 
Rockall Trough. The low salinity is caused by the presence of small amounts 
of Antarctic Bottom Water in the LDW. In 2007 the LDW reached further north, 
and could also be observed at the CTD station on the AR7E section.
