# Ice brine chlorophyll-a concentrations, from ice core holes, Southern Ocean, GLOBEC # C. Fritsen, Desert Research Institute # RVIB Nathaniel B. Palmer cruise NMP02-04, July-Sept 2002 # * chla = chlorophyll-a, micrograms per liter (ug/l) # * lat = latitude reported in decimal degrees south # * lon = longitude reportred in decimal degrees west # * bot_depth = depth to bottom of ice core hole in meters # The following are notes/comments about this file: # Corrections have been applied to the data per Fritsen's e-mail of 12/03/03. # The abbreviation Crys. Sd. in station field stands for Crystal Sound. # # Methods: Brine samples were collected from auger holes that were drilled into # sea ice using a 2 inch kovacs coring auger. Brine that flowed into the bottom # of the hole was collected using a tygon tubing attached to a 60 cc syringe. # Cholorophyll-a concentrations were determined using the techniques as reported # in previous submissions of ice core and water column data. Multiple sample # numbers reflect replicate samples taken from the same hole. # # The following fields have been added to this data set: cruiseid, year, month_gmt, # day_gmt. # The fields beyond chla should not be served. One could argue that ice_sta should # be omitted also. # cruiseid year station___ event____ month_gmt day_gmt lat____ lon____ ice_sta sample_id bot_depth chla GMT date Julian date NBP0204 2002 Crys.
