From: Increasing nitrogen limitation during summer in the List Tidal Basin (Northern Wadden Sea)
Resource limitation map according to Cloern (1999). Diamonds show positions of light and nutrient measurements the List Tidal basin in 1985 (left) and 2005 (right); Numbers above diamonds indicate respective months. Areas of R > 10 indicate strong light limitation, areas of R > 0.1 strong nitrogen limitation, and areas of 10 > R > 0.1 indicate co-limitation of light and nitrogen
