Adjective modifier

• subpolar: Water in the subpolar gyre cooled between the two 20-year periods due to the decrease in surface heat input.

• subtropical: However, if no relaxation is applied, the model shows 5° of surface warming over 5 years in the subtropical gyre.

• oligotrophic: This implies that the food web structure and primary productivity are uncoupled in the oligotrophic gyres.

• sub-tropical: The main focus of the project is the sub-tropical gyre.

• tidal: These include local wave climate; sources of sediment feed and the role of coastline orientation in creating an anticlockwise tidal gyre.

• Atlantic: They then aim to investigate the relationship between primary production and community structure within the Atlantic sub-tropical gyres.

Modifies a noun

• circulation: Need to identify relative importance of overturning versus gyre circulation.

• component: Similarly with heat transport, the gyre component varies little seasonally whereas the overturning part varies much more.

Noun used with modifier

• ocean: AMT sampling covers almost the entire gradient of oceanic productivity from oligotrophic ocean gyres to seasonally high productive high latitude and equatorial upwelling waters.

• sub-polar: This propagates around the Pacific sub-polar gyre and warms up whole gyre.
