How carrier and amphibious groups divide sea control and landing duties

What doctrine governs the relationship between carrier groups and amphibious groups?

The carrier group wins and protects theater access, while the amphibious group uses that sea control to place and sustain forces ashore.

A carrier group normally stands farther offshore, striking targets and securing the surrounding sea and air space. The amphibious group advances once that protection allows it to approach, then lands troops and creates an entry point for the wider land campaign. Close escorts and bombardment forces concentrate around the assault shipping during the vulnerable approach. A later follow-up distinguishes tactical assault shipping from lift and sustainment groups, using the Falklands example of 3 Commando Brigade's assault followed by Army reinforcement delivered through the lodgment already created.
