Dissolved Oxygen Analysis

Florida's surface water criteria for dissolved oxygen (DO) in predominantly marine waters is found in Rule 62-302.533, Florida Administrative Code. Station-by-station analysis of the continuous water quality data that does not meet this criteria are categorized as events, which are displayed in the table below by Aquatic Preserve (AP) station and year. Click the 1-day, 7-day or 30-day link (if available) to view the corresponding graph displaying percent saturation of dissolved oxygen (DO%), DO_event, and the event average. Please allow several seconds for the graphs to render. Straight lines in the graphs represent the duration of the criteria exceedance (see criteria summary below).

Disclaimer: The table and graphs should not be used to directly assess water quality of the water body in which the datasonde is located. Florida criteria assessments are conducted on an entire waterbody, not on a station-by-station basis.

Table Key

Gray box = no DO measurements were recorded for that station and year.
DO criteria for Florida marine waters (62-302.533 F.A.C.) is summarized below:

1-day average criteria (daily):       DO% < 42% in no more than 10% of the values
7-day average criteria (week):      DO% < 51% no more than once in any 12-week period
30-day average criteria (month): DO% < 56% no more than once per year

Numbers to the right of the colon represent the number of occurrences that exceed the criteria above (i.e., "1-day: 2" means there were two occurrences that year of DO% dropping below 42% within a 24-hour period).
The number listed after "of" represents the total number of DO sampling days within the given year, which may vary based on data gaps.

Note: Data marked as suspect during secondary QA/QC were not used in these calculations.
