Ice Buoy Times Series Plots
The time series plots are separated by sensor type, producing three plots for temperature, heating cycle 1 and heating cycle 2 data. Nan data values appear as white, with time stamps with only Nan values being removed. The sensor elevation is set with zero being ice level at the time the sensors are deployed. The temperature data has a sampling rate of 6 hours and each heating cycle has a sampling rate of 24 hours. The plots break after one year of data from the start of the data requested or when the sensors are redeployed. For best results it is recommended to choose a minimum of 10 days.

Data Product Options
Quality Control
Raw Data
When this option is selected, raw data will be supplied in the data products: no action is taken to modify the data. In general, all scalar data is associated with a quality control flag. These flags are stored adjacent to the data values.
Oceans 3.0 API filter: dpo_qualityControl=0
Clean Data
Selecting this option will cause any data values with quality control failures (QAQC flags 3, 4 and 6) to be replaced with NaNs. If the do not fill data gaps option is selected, data values with quality control failures will be removed. For all data products, when resampling with the clean option, any data with quality control failures are removed prior to the resampling (this rule applies to all resampling types: average, min/max, etc).
This is the default option for all data products.
Oceans 3.0 API filter: dpo_qualityControl=1
File-name mode field
'clean' is added to the file-name when the quality option is set to clean data.
Formats
This data is available as a PNG image or PDF file.
Example
Here is an example pdf: CambridgeBay_SafePassageBuoy_IceBuoy_20160227T000000Z_20160430T235959Z-Heat1-736413.6288.pdf. The naming convention goes as ' -"sensor type" ' in the MODE field, see dp home.
Note: The data show is test data.
