Measurements of dissolved inorganic carbon and pH on the total scale were also made as quality control checks. GLODAPv2 hinted at a potential offset between laboratories in the Pacific Ocean. We hypothesized that if non-negligible amounts of organic alkalinity were present, the different methods could be titrating different amounts leading to differences between the methods. The results show that any offset is within the uncertainty of the analytical precision and presence of organic alkalinity in open ocean waters remains inconclusive.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nsample_ID (unitless)\nStation (unitless)\nCast (unitless)\nNiskinBottle_No (unitless)\nDate (unitless)\ntime_unitless (Time, unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nCTD_Salinity (unitless)\nCTD_Salinity_flag (unitless)\nBottle_Salinity (unitless)\nBot_Sal_flag (unitless)\nCTD_Pressure (decibars (db))\nTotal_Alkalinity_Single_Step_method (micromoles per kilogram of seawater (umol/kg_sw))\nTotal_Alkalinity_Single_Step_Method_flag (unitless)\nFinal_pHt_for_Single_Step_method_TA (total scale)\nTotal_Alkalinity_Open_Cell_Method (micromoles per kilogram of seawater (umol/kg_sw))\n...

Water samples were all collected in West Maui in and around reef systems that were within and adjacent to the burn zone of the Lahaina fires. These samples were collected by boat transect, shoreline grab sampling, and autonomous sampling devices. Some autonomous sampling data from before the fire event are also included. The aim of these data is to understand the effects on coral reef health in response to the urban fires that occurred in August of 2023. Samples were collected by a collaborative effort of scientists Dr. Andrea K Kealoha, Dr. Craig Nelson, Dr. Eileen Nalley, and Dr. Nicholas Hawco.\n\ncdm_data_type = Other\nVARIABLES:\ndate (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nISO_DateTime_Local_HST (unitless)\ncollection (unitless)\nuniqueID (unitless)\nstation (unitless)\nsampling_trip (unitless)\ndescription (unitless)\ntide (unitless)\nstation_platform (unitless)\nstation_category (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nmetal (unitless)\nfcm (unitless)\nfdom (unitless)\nhlb (unitless)\ndoc (unitless)\n...
