Data Entry


Once you have monitored your Seagrass-Watch site, you can now enter the data collected into a downloadable Microsoft Excel spreadsheet and submit via email.

To enter and submit data, follow the following steps:


1 Select your seagrass geographic bioregion from the image below, and download the relevant web data entry spreadsheet
  Region 1: Temperate North Atlantic (North Carolina, USA to Portugal)
  Region 2: Tropical Atlantic (including the Caribbean Sea, Gulf of Mexico, Bermuda, the Bahamas, and both tropical coasts of the Atlantic)
  Region 3: Mediterranean (including the Mediterranean Sea, the Black, Caspian and Aral Seas and northwest Africa)
  Region 4: Temperate North Pacific (Korea to Baja, Mexico)
  Region 5: Tropical Indo-Pacific (East Africa, south Asia and tropical Australia to the eastern Pacific)
  Region 6: Temperate Southern Oceans (New Zealand and temperate Australia, South America, and South Africa)


Save the spreadsheet file to your computer before you begin data entry. We suggest changing the file name to the site code and the sampling date.

  • For example, if the site was Burrum Heads 1, and it was sampled on 09 February 2005 then the filename would be "BH1_09Feb05.xls"

The spreadsheets are a similar layout to the standard datasheets. Each transect has it's own worksheet. To select the appropriate worksheet, click on the tab at the bottom


To enter data, select each cell with your mouse. You can jump between cells by using the TAB button on your keyboard.


First enter the name of the observers and the sampling date.

6 Enter the location and site code.
  • For the above example, the location is "Burrum Heads" and the site code is "BH1".

Enter the time you started sampling the transect and the time you finished.

  • Times are entered at 24 hr with the hour separated from the minutes by a colon.
    For example. if the time was half past one in the afternoon, the time entered would be "13:30".

If you had a GPS (Global Positioning System) at the monitoring site, the latitude and longitude of the transect start

9 Enter the data for each quadrat
  • Sediment: enter by the dominant grain size first, separating sediment categories by a forward slash. For example, if the quadrat was predominantly mud with some sand, then the data would be entered as "Mud/Sand".  Please do not use abbreviations "M/S" when entering into the spreadsheet.
  • Comments: Enter information (including counts) of any features which may be of interest. For example, "sea cucumbers (x2), sea urchin (x1), evidence of turtle cropping"
  • Photograph: type in "True" if you took a photo of the quadrat
  • % cover: enter the total percent cover of seagrass within the quadrat
  • % cover by species: enter the percentage cover that each species contributes to the total cover


CR = Cymodocea rotundata

CS = Cymodocea serrulata

EA = Enhalus acoroides

HC = Halophila capricorni

HD = Halophila decipiens

HM = Halophila minor

HO = Halophila ovalis

HP = Halodule pinifolia

HS = Halophila spinulosa

HT = Halophila tricostata

HU = Halodule uninervis

SI = Syringodium isoetifolium

TC = Thalassodendron ciliatum

TH = Thalassia hemprichii

ZC = Zostera capricorni


  • Canopy: enter the three canopy heights of the dominant strap leaf species (the average will calculate automatically)
  • % Algae: enter the percent cover of maco-algae in the quadrat. Macro-algae are seaweeds that are not attached to seagrass leaves and may even overlie the seagrass shoots. The combined seagrass and algae cover may be greater than 100%.
  • Epi %: Enter the percentage cover of epiphytes on the total seagrass leaves.

Enter the latitude and longitude of the transect finish


Enter any general comments about the transect or site


Repeat steps 5 to 10 for the remaining transects

All raw data collected in the Seagrass-Watch program is the property of the individual/group/institution (principal) who collected it, and Seagrass-Watch HQ is custodian. When a Principal (data collector) submits data to Seagrass-Watch HQ, it does so under the proviso that Seagrass-Watch HQ can conduct a data quality assessment as part of the Seagrass-Watch program’s QAQC protocols and that the validated data is available for condition and trend reporting at location, regional, state, national and global scales (e.g., State of the Environment Queensland, State of the Environment Australia and State of the Environment GBR). Copies of raw data are provided to third parties only when permission from the principal is provided.

Ownership of data within the Seagrass-Watch program is determined by mutual agreement based on who is collecting the raw data, whether the data undergoes a quality assessment as part of Seagrass-Watch QAQC protocols and the funding sources that support the monitoring.

  • Ownership (intellectual property rights) of the Raw Data lies with the Principal (data collector). Seagrass-Watch is custodian of the Raw Data.
  • Ownership (intellectual property rights) of the Validated Data is shared between the Principal and Seagrass-Watch Ltd.

All data interpretation is conducted by Seagrass-Watch HQ. This ensures that the interpretation of data is consistent, unbiased and of scientific merit. Seagrass-Watch HQ also encourages peer review and assessment of published results.

Apart from the regional & statewide report cards (e.g. SoE), the data has also been used for:

  • understanding and responding to impacts from catchment runoff (Campbell & McKenzie 2004), coastal developments (e.g. marina constructions) and dredging proposals.
  • Understanding natural levels of change and supporting marine habitat conservation (e.g. GSS Ramsar Wetland, Cooloola World Heritage area, and Great Sandy Marine Park)




Seagrass-Watch HQ also ensures the QAQC protocols for the program are followed and that the program is producing data of high quality, ensuring time and resources are not wasted. Quality assurance refers to the management system by which data is collected, organised, documented and evaluated. Quality control refers to the technical means by which error is controlled.

The five indicators of QAQC that the program uses are:

  • Precision: This is the degree of agreement among repeated measurements. This is controlled by conducting scientific training & using calibration sheets.
  • Accuracy: This measures how close results are to a true or expected value. To do this the program requests voucher specimens of seagrasses, conducts refresher scientific training & requires observers to make photographic records (ie 27% quadrats sampled are photographed)
  • Representative ness is the extent to which measurements actually represent the whole population at the time an observation was made. In the program, this is controlled by choosing sites which are representative of the location.
  • Completeness is the comparison between the amount of valid, or useable, data originally planned to collect, versus how much was collected. This is ensured by employing standardised scientific methods (developed in consultation with community volunteers) which are simple and easy to use.
  • Comparability is the extent to which data can be compared between sample locations or periods of time within a project or between projects. This is ensured by using standardised methods and calibration sheets and conducting regular refresher scientific training.
