Hi Alex,

Regarding NCEI cruise metadata and files for cruise 36AE19950209, here are the actions to be made on the NCEI website:

Changes for data files on the NCEI file repository for 36AE19950209:
It should include the files contained in the Google Drive folder for the cruise: https://drive.google.com/drive/folders/1ioQu1kg1sEqORA1EGVeDX4_6Z_p30Xxw
Replace the data file. It has the file named 36AE19950209.exc.csv and it shoudl have the file named 36AE19950209_hy1.csv.
Upload the map (file: map_cruise_36AE19950209.tif).
Remove the metadata file (file: HCMR_OTR5_Cruise_Meta.html).
Remove the README file (file: README).
Changes for metadata information on NCEI for 36AE19950209:
The INVESTIGATORS and Principal Investigators should only be Emmanuel Papageorgiou - National Centre for Marine Research, Athens, Greece.
"VARIABLES/PARAMETERS" fields:
For Dissolved Inorganic Carbon:
The abbreviation should be TCARBN.
Add the field "Sampling instrument:    Niskin Bottles".
Update the field "Detailed sampling and analyzing information:" with: "The seawater samples for the determination of ALKALI and TCARBN were drawn into 500-1000 mL borosilicate glass bottles sealed with glass stoppers according to the collection methods of DOE (1994). The samples were poisoned with saturated mercuric chloride solution (Poison Volume (mL): 0.2-0.5 mL depending on sample volume) to prevent further biological activity, stored at room temperature away from light and analysed on shore as soon as possible. ALKALI and TCARBN measurements were preformed simultaneously using the potentiometric acid titration method in a closed cell, which was maintained at constant temperature (25 ± 0.1 ºC) by a thermostated water bath. The ionic strength of the hydrochloric acid solution (0.1 N) used for the titrations was adjusted with NaCl in order to be similar to that of the samples. The hydrochloric acid solution was added with an automatic burette (ABU 80, Radiometer) and the progress of the titration was monitored using a glass electrode/reference electrode pH cell (PHM-84, Radiometer). The burette and the pH-meter were interfaced with a computer using data-acquisition software. The ALKALI corresponds to the carbonic acid endpoint and the TCARBN concentration is computed by the difference between the two endpoints, which were calculated using a modified Gran approach, a procedure recognized by DOE (1994). The analytical precision for TCARBN based on duplicate seawater samples was 6.3 µmol Kg-1. The accuracy of TCARBN was assessed by CRM measurements and was ±5.6 µmol Kg-1. The analytical precision for ALKALI based on duplicate seawater samples was 5.3 µmol Kg-1. The accuracy of the ALKALI was assessed by CRM measurements and was ±3.2 µmol Kg-1. Batch #24 supplied by Dr A.G. Dickson (SIO,USA) were used to control the analytical precision.".
This parameter should appear where the parameter TCARBN appears (after the nutrients), and the information contained in the parameter TCARBN that appears later in the list should be merged with the information of Dissolved Inorganic Carbon.
For Total alkalinity:
The abbreviation should be ALKALI.
Add the field "Sampling instrument:    Niskin Bottles".

This parameter should appear where the parameter ALKALI appears (after the TCARBN), and the information contained in the parameter ALKALI that appears later in the list should be merged with the information of Total alkalinity.
For CTD_TMP:
 It should be named CTDTMP.
The Controlled vocabulary name should be CTD WATER TEMPERATURE.
Add the field "Researcher name: E. Papageorgiou, A. Theocharis, D. Georgopoulos (HCMR)".
For SALNTY
Add the field "Researcher name: E. Papageorgiou, A. Theocharis, D. Georgopoulos (HCMR)".
Add parameter Dissolved Oxygen with the following fields:
Abbreviation:    OXYGEN
Unit:    UMOL/KG
Controlled vocabulary name:    Dissolved Oxygen
Observation type:    Bottle discrete
In-situ / Manipulation / Response variable:    in-situ
Researcher name:    E. Souvermezoglou, E. Krasakopoulou (HCMR)
For PHSPHT:
The name of the parameter should be changed to Phosphate (abbreviation should still be PHSPHT).
Add field "Observation type: Bottle discrete".
Add field "Researcher name:    E. Souvermezoglou, E. Krasakopoulou (HCMR)".
For SILCAT:
The name of the parameter should be changed to Silicate (abbreviation should still be SILCAT).
Add field "Observation type: Bottle discrete".
Add field "Researcher name:    E. Souvermezoglou, E. Krasakopoulou (HCMR)".
For NO2+NO3:
The name of the parameter should be changed to Nitrate

Add field "Observation type: Bottle discrete".
Add field "Researcher name:    E. Souvermezoglou, E. Krasakopoulou (HCMR)".
Add field "Provider Keywords" within "Theme keywords" and include "CARIMED" as the provider keyword.
