Each year, the Association for the Sciences of Limnology and Oceanography (ASLO) presents the John H. Martin Award to one paper that has led to fundamental shifts in research focus and interpretation of a large body of previous observations. The 2024 John H. Martin Award is being presented to “Lake metabolism: Relationships with dissolved organic carbon and phosphorus” by Hanson et al. for showing that lakes experience seasonal net heterotrophy, except in cases of high phosphorus and high primary production. The Martin Award will be presented to Dr. Paul Hanson (University of Wisconsin-Madison, Center for Limnology) on behalf of the co-authors during the 2024 ASLO Summer Meeting in Madison, WI, USA in June.

Hanson et al. (2003), published in Limnology and Oceanography, was a transformative publication that helped advance understanding of lake nutrient cycling dynamics. The researchers sampled 25 Northern Highland Lakes and measured dissolved oxygen, carbon dioxide, and phosphorus to show the balance between primary production and respiration. They found that external carbon sources, such as leaf litter and other terrestrial organic matter, strongly influence whole-lake metabolism, except when primary production and total phosphorus concentrations lead to autotrophic conditions. The methods used were expansive and included innovative in situ sampling techniques and systems models that quantified and distinguished internal and external carbon sources. The sensors and modelling methods were especially influential and provided the foundation for prolific research programs at North Temperate Lakes Long Term Ecological Research (NTL-LTER) and the Global Lake Ecological Observatory Network (GLEON).  This work has laid the foundation for future lake metabolism studies, as evidenced by gaining over 480 citations over the past twenty years.

ASLO President Pat Glibert says, “Almost twenty years later, the seminal work of Hanson et al. proved critical for understanding carbon cycling in lake environments. This transformative paper provided the foundation for several methodological advancements in the field and greatly influenced the trajectory of limnological research.”
