Nutrient data UPDATED 7/7/2016 - MATFILE was created
----------------------------------------------------
(1) File name: GM_nuts_2003_2016.mat
    Variables in this mat file:
    GM_nuts_2003_2016_data, variables_name_number_units, ship_ID_and_name;
(2) Matfile includes all the 2003-2016 updated data;
(3) Temperature, Salinity and Pressure are the only CTD data included;
(4) Used time is UTC;
(5) NH4 data considered "bad" (not reasonable) for the following cruises:
   2003 oc391, 2004 oc402, 2005 oc412 and 2006 oc425 and was replaced with NaNs;
(6) Some additional corrections made while creating matfile:
    - data negatives equated to zero:
       NO3: EN476, sts 32 and 84, 10m.
       CHL: OC460, st 1, 20m.
    - OC465, st 105, 175m Longitude mistake (one depth only).
