# 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 temporal 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}

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/intermediate/_summarized_data_files", "ts.csv"))

```

## EDA clean data

```{r ts_EDA_clean, eval=FALSE}

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

rm(eda)

# HydroC CO~2~ data (th)

## Read data

Originally, 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. Those data are read-in here. However, later, the post-processing was repeated based on a cleaned data set.

```{r read_th_post_processed_by_manufacturer}

# Read Contros corrected data file, based on all recordings

th <-
  read_csv2(here::here("data/input/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",
                          "Signal_raw", "Signal_ref", "T_sensor",
                          "pCO2_corr", "Runtime", "nr.ave")) %>% 
  mutate(date_time = dmy_hms(date_time),
         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}

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


th %>%
  select(date_time, pCO2_corr, deployment) %>%
  write_csv(here::here(
    "data/intermediate/_summarized_data_files",
    "th_pre_cleaning.csv"
  ))

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}


# add counter for date_time observations

th <- th %>%
  add_count(date_time)

# find triplicated time stamp and select only first observation, and merge

th_no_triple <- th %>%

# find duplicated time stamps and shift first by one second backward, and merge

  ungroup()

th_duplicated_clean <-
  full_join(th_duplicated_first, th_duplicated_second) %>%
  arrange(date_time)

th <- full_join(th_no_duplicated, th_duplicated_clean)

th %>%
  distinct(date_time)

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

# 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)

```

## Flush and Zeroing identification

```{r Identify_Zeroing_Flush_th}


# Zeroing ID labeling

th <- th %>%

    duration = date_time - start,
    Flush = if_else(Zero == 0 &
                      duration < parameters$HC_flush_duration, "1", "0")

```
