Thermohaline Circulation

Edit: thank you for getting this puzzle featured on Cracking the Cryptic!
This is my first loop puzzle, which I made for another Weekly Scojo prompt: "make a loop puzzle with at most 10 clues". I hope you enjoy it!
- Standard Sudoku rules apply.
- Loop: shade some cells to form a 1-cell-wide orthogonally connected loop. The loop may not touch itself orthogonally, but can touch itself diagonally.
- Non-loop cells form several orthogonally connected groups. Such a group of size N contains exactly the digits from 1 to N.
- Thermo-sightline arrows: Each cell with an arrow (called an 'arrow cell') lies on the loop. The digit in an arrow cell is the number of visible loop cells in the indicated direction, where non-loop cells obstruct vision. (The arrow cell is not included in this count). Additionally, digits increase along loop cells seen by an arrow, starting with the digit in the arrow cell.
Solve Thermohaline Circulation on Sudokupad!
Solution code: Non-loop digits from the top two rows (no spaces).

Amazing puzzle! I loved how there was some great logic for both loop and non-loop cells.

Outstanding construction! Interesting deductions all the way through to the end, especially with the non-loop cells.

Loved the ramifications of the non-loop cell rule, and the variety of deductions it lead to.
