1. How big is ICES Statistical Rectangles?55 km longitude by 55 km latitude
2. What is the system originator?International Council for the Exploration of the Sea (ICES)
3. What is the development era?Initiated in the 1970s
4. Why do the rectangles get smaller or bigger as you go north or south?Because the Earth is round, the distance between lines of longitude gets shorter near the poles, so the rectangles are a bit wider in the south and a bit narrower in the north.
5. How do scientists name each rectangle?They give each row a number from 01 to 99 and each column a letter‑number code like A0, B1, etc., so a rectangle might be called 37F3.
