_{This is part 37 of the puzzle series Around the World in Many Days. Each part is solvable on its own.}

Dear Puzzling,

This is an Aquarium puzzle. The grid is divided into “rooms”. Shade some cells in the grid so that every room can be divided by a horizontal line so that every cell on the line and below it is shaded, and every cell above the line is unshaded. Fully shaded and fully empty rooms are allowed. Numbers outside the grid indicate how many shaded cells are in the direction of the arrow.

Small blue numers in the grid form a diagramless crossword. The answers to the clues a–k are in alphabetical order. Only the starting points of the clues are given in the grid; you must determine which clue starts at which number. The direction of each clue is given by the arrow next to it. Some cells will be left empty in the grid.

Today, I have taken a boat tour to explore a snow-covered environment full of rich wildlife. I have seen walrus, polar bears, musk oxen, Arctic foxes and enormous flocks of seabirds. I am definitely making good progress, but there’s still a long way to go before I get to complete my round-the-world trip. Can you guess where I am?

Love, Gladys.
