After an uncomfortable night we had gusts of up to 50 knots and swell of between 8 and 10 meters today making it another lumpy day.  The masters eased back our speed to an average of 6.5 knots to allow for this weather and we crossed the half way point between Cork and St. Johns, Newfoundland this morning at 10:30.  Progress is good although everyone on board agrees it would be nice to have some calmer weather!

Air temperature rose again today and this evening is 10.30 with the water temperature at 12.72.

Our track will take us through areas that are 100% covered by Argo floats monitored under JCOMMS (Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology) so we will not deploy the Argo floats on the outward bound leg. 

We will hope to deploy on the homeward bound leg.
Emily, Conor and Alex continued bird and whale watching respectively throughout the day.  Unfortunately no whales were around today but three puffins and approximately fifty kittiewakes were recorded.

XBT Temperature Plot
 Two XBT’s were carried out during the day and deployments are stopped again tonight due to the weather conditions  Processing of this data is being carried out and a temperature profile can be seen in Figure 1 from a station taken close to the mid Atlantic ridge yesterday.

The weather is to improve over the coming 24hrs and will be welcomed by all on board.
