The area where oxygenated substrates (light brown) change to deoxygenated substrates (black, often smelly). This depth will vary with water movement and animal activity. Oxygen penetrates further with the actions of burrowing animals and increased water movement. This layer can influence what species live where in soft sediments.
Enter the value (in mm) as the average of the four core samples

Enter nearest town first, followed by the shore name.
Give a brief description of the site and describe any possible influences that might be important to the plants and animals in the area (e.g. weather, rocky headland with surf beach 3 km to south; freshwater creek 50 m to the north; upper shore modified with harbour wall; popular site for paua collectors, etc.).
Write a brief description of the site and describe any potential influences that are not directly related to tidal movement (e.g. rocky headland with surf beach 3 km to south; freshwater creek 50 m to the north; upper shore modified with harbour wall; popular site for paua collectors, etc.)
Position of the Marine Metre Squared area on the shore
The depth of your footprints in the sediment are a good guide to the type of sediment. How far did your feet sink when walking along the shore?
The number of animals or percentage cover of seaweeds for each species in the Marine Metre Squared area
The number of animals or percentage cover of seaweeds for each species per 0.25 m2 quadrat
Distance separating each quadrat sample given in meters.
The number of the quadrat on the transect from Q1 (highest shore level) to Q11 (lowest)
The type of surface where the Marine Metre Squared area was completed:
Enter the substrate that covered more than 50% of the quadrat. Select from
The amount of exposure to waves and surf e.g. open sea = exposed; sheltered bay or harbour = sheltered.
Site aspect: the general compass direction that the shore faces.
Enter at least 3 characters to bring up a search of all scientific, common and maori names for the species.
The first drop-down displays species common names.
The second drop-down displays corresponding scientific names, when available.
Display results for a particular date (data collection began in 2012).
Display results from Marine Metre Squared or Secondary Schools Transect Survey.
