Ice Buoy Times Series Profile Plots

The time series plots are separated into three groups of sensors, producing plots for temperature, heating cycle 1 and heating cycle 2 data. Not-a-Number (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. In the deployment for 2016 near Cambridge Bay, the temperature data has a sampling rate of 6 hours and each heating cycle has a sampling rate of 24 hours; this may change in other deployments. The plots break after one year of data from the start of the data requested or when the sensors are redeployed. Because of the low sample rate, it is recommended to choose a minimum of 10 days.

Data Product Options

Quality Control

For time series scalar data:

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. See an example plot below (PNG format), note that this is poor quality test data.

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 the Data Products home page for a description of the file-naming convention.
