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

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:

• Rock: solid, unmoving surface like rock or boulders.
• Mixed: mixture of rocks and loose materials like cobbles, gravel and sand.
• Soft: loose material like sand and mud.

Enter the substrate that covered more than 50% of the quadrat. Select from

• Rock: stable hard surface, continuous basement rock or large immovable boulders.
• Cobble: fist to head sized rocks that can be moved by hand.
• Mixed: loose stones of different sizes.
• Pool of water: a rock pool.

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.

Take a picture of your square from directly above so that you can compare changes to the plants and animals living there over time.

Take a photo to show the the profile of the shore and positions of your transect line. Note any significant habitat features on the profile that might affect organisms’ distributions in particular quadrats (e.g. rockpools, large boulders, patches of sand, etc.).
