In this document, raw data files are read, merged into one file with harmonized column names and written as summarized data file.


# Sea-Bird SBE 16 sensor data (ts)

CTD sensor data including recordings from auxiliary pH, O~2~, Chla and pCO~2~ sensors were recorded with a measurement frequency of 15 sec. (In addition, pCO~2~ data were also internally recorded on the Contros HydroC instrument with higher tempral resolution and will later be used for further analysis after merging with CTD data.)

## Write summary file

Relevant columns were selected and renamed, only observations from regular stations (P01-P13) and transects (T01-T13) were selected and summarized data were written to file.

```{r ts_column_subsetting_writing_summary_file, eval=FALSE}

ts <- ts %>% 
  select(date_time,
         ID,
         type,
         station,
         dep,
         sal,
         tem,
         pCO2_analog)

# ts <- ts %>% 
#   filter( !(station %in% c("PX1", "PX2", "TX1", "TX2") ))

ts %>% 
  write_csv(here::here("data/_summarized_data_files", "ts.csv"))

rm(ts)
```

## EDA clean data


```{r reopen_ts_data}
ts <- read_csv(here::here("data/_summarized_data_files", "ts.csv"),
               col_types = cols(pCO2_analog = col_double()))
```


```{r ts_EDA_clean, eval=FALSE}

source("code/eda.R")
eda(ts, "ts_clean")

rm(eda)
```

# HydroC CO~2~ data (th)

## Read data

HydroC pCO~2~ data  were provided by KM Contros after applying a drift correction to the raw data, which was based on pre- and post-deployment calibration results. 

```{r read_th_post_processed_by_manufacturer, eval=FALSE}

# Read Contros corrected data file

th <-
  read_csv2(here::here("Data/TinaV/Sensor/HydroC-pCO2/corrected_Contros",
                       "parameter&pCO2s(method 43).txt"),
            col_names = c("date_time", "Zero", "Flush", "p_NDIR",
                          "p_in", "T_control", "T_gas", "%rH_gas",

         Flush = as.factor(as.character(Flush)),
         Zero = as.factor(as.character(Zero)))

```

## Deployment identification and subsetting

Individual deployments (periods of observations with less than 30 sec between recordings) were identified and relevant deployment periods were subsetted. This procedure removes only recordings attributable to sensor testing and set-up.

```{r identify_select_th_deployment, eval=FALSE}

th <- th %>% 
  arrange(date_time) %>% 
  mutate(deployment = cumsum(c(TRUE,diff(date_time)>=30)))

th <- th %>% 
  filter(deployment %in% c(2,6,9,14,17,21,23,27,31,33,34,35,37))

```

## Removal of duplicated time stamps

```{r remove_duplicated_timestamp_th, eval=FALSE}


# add counter for date_time observations

th %>% 
  distinct(date_time)

rm(list=setdiff(ls(), "th"))

# remaining duplicates are observations where other observations with a +/- 1 sec timestamp exist
# for those cases, only the first duplicated observation is selected (similar to triplicate treatment)


th %>% 
  distinct(date_time)

th <- th %>% 
  select(-n) %>% 
  add_count(date_time)

unique(th$n)
