The Methods for Estimating Lake Volume, Mean Depth, and Maximum Depth in European Standard EN 16039:2011 Are Flawed and Should Not Be Used
1 Introduction Bathymetric surveys are time consuming and prohibitively expensive for large numbers of lakes—a major challenge for evaluating lake ecological status because volume and maximum depth are key constraints on many ecosystem characteristics (Boon et al. 2019; Cael, Heathcote, and Seekell 2017; Cael and Seekell 2022).
Stronger together: Making space on team science for diverse career paths
Register NOWRemaining time: 7 DAYS | 08 HRS | 54 MINS Chelsea Wood, Ph.D.Speaker Annika Jenmalm Jensen, Ph.D.Speaker David Seekell, Ph.D.Speaker Erik Lindahl, Ph.D.Speaker Sacha Vignieri, Ph.D.Moderator The drive to push exploration of what we know about life is an inspiration to pursue science. However, while the research forefront keeps pushing the boundaries of what is possible, structures for scientific career paths have stagnated.
Lake morphometry moderates the relationship between water color and fish biomass in small boreal lakes
In this study, we evaluated patterns of fish biomass based on comparative analysis of small boreal lakes across gradients of light extinction, a proxy for DOC concentration (e.g., Pérez‐Fuentetaja et al. 1999 ; Bukaveckas and Robbins‐Forbes 2000 ; Seekell et al. 2015 a ), and mean depth.
Lake morphometry moderates the relationship between water color and fish biomass in small boreal lakes
Lake morphometry may moderate the effects of water color on fish biomass in boreal lakes, but empirical evidence is scarce because there are a limited number of lakes for which both water color and bathymetry have been measured. We evaluated variations in catch‐per‐unit‐effort (CPUE), an indicator of fish biomass, across orthogonal gradients of light extinction and mean depth in 16 small Swedish lakes (mean depth 1.7–4.8 m, surface area 1–10 ha).

Lake carbon cycling is influenced by external factors controlling the transfer of mass (e.g. carbon, nutrient) and energy (e.g. light, heat) on lake processes (e.g. primary production, respiration, greenhouse gases emissions), either directly or through the terrestrial landscape (Leavitt et al. 2009; Lapierre et al. 2015).

Passing the point of no return
In the field of ecology, regime shifts are massive changes in function and character that occur when an ecosystem passes a tipping point. Regime shifts sometimes have severe consequences for human well-being through losses of ecosystem services, including desertification in arid regions and marine fisheries collapses (1, 2). These changes are difficult to predict and sometimes impossible to reverse (2).
