Lakes from Minnesota to Maine are usually still frozen over at this time of year, as signs of spring slowly emerge across the country’s northern tier.

Instead, the ice is breaking up or is already gone on many lakes with more than a century of records. So-called ice-out — when waters become navigable for boats again — is happening earlier than ever witnessed.
These lakes are usually still frozen over. See how they look now.

Eremenko's conjecture, wandering Lakes of Wada, and maverick points
We develop a general technique for realising full closed subsets of the complex plane as wandering sets of entire functions. Using this construction, we solve a number of open problems. (1) We construct a counterexample to Eremenko's conjecture, a central problem in transcendental dynamics that asks whether every connected component of the set of escaping points of a transcendental entire function is unbounded. (2) We prove that there is a transcendental entire function for which infinitely…

The entire St Lawrence Seaway system will open for transiting of commercial ship traffic on Mar 22, 2024. Given that the system only closed on Jan 16, 2024, this is the shortest closure ever for the Great Lakes Waterways and Seaway system. #ClimateChange

Calcium loss turning lakes to 'jelly'
New research on a number of Canadian lakes show that historical acid deposits as a result of industry have greatly reduced calcium levels in the water - dramatically impacting populations of calcium-rich plankton such as Daphnia water fleas that dominate these ecosystems.

Viscoelastic mechanics of tidally induced lake drainage in the Amery grounding zone
Drainage of supraglacial lakes to the ice-sheet bed can occur when a hydrofracture propagates downward, driven by the weight of the water in the lake. For supraglacial lakes in the grounding zones of Antarctic glaciers, the mechanics of drainage is complicated by their proximity to the grounding line. Recently, a series of supraglacial lake-drainage events through hydrofractures was observed in the Amery Ice Shelf grounding zone, East Antarctica. The lake depth at drainage varied considerably b…

Nature-Guided Cognitive Evolution for Predicting Dissolved Oxygen Concentrations in North Temperate Lakes
Predicting dissolved oxygen (DO) concentrations in north temperate lakes requires a comprehensive study of phenological patterns across various ecosystems, which highlights the significance of selecting phenological features and feature interactions. Process-based models are limited by partial process knowledge or oversimplified feature representations, while machine learning models face challenges in efficiently selecting relevant feature interactions for different lake types and tasks, especi…

Reproducible data science over data lakes: replayable data pipelines with Bauplan and Nessie
As the Lakehouse architecture becomes more widespread, ensuring the reproducibility of data workloads over data lakes emerges as a crucial concern for data engineers. However, achieving reproducibility remains challenging. The size of data pipelines contributes to slow testing and iterations, while the intertwining of business logic and data management complicates debugging and increases error susceptibility. In this paper, we highlight recent advancements made at Bauplan in addressing this cha…

Monitoring the coastal area of the Venice Lagoon is of significant importance. While the impact of global warming is felt worldwide, coastal and littoral regions bear the brunt more prominently. These areas not only face the threat of rising sea levels but also contend with the escalating occurrence of seaquakes and floods. Additionally, the intricate ecosystems of rivers, seas, and lakes undergo profound transformations due to climate change and pollutants. Employing devices like the SENSWIC…

Global plastic pollution treaty talks hit critical stage in Canada
Thousands of negotiators and observers representing most of the world’s nations are gathering in the Canadian city of Ottawa this week to craft a treaty to end the rapidly escalating problem of plastic pollution. Each day, the equivalent of 2,000 garbage trucks full of plastic are dumped into the world’s oceans, rivers and lakes. People are increasingly breathing, eating and drinking tiny particles of plastic. Some at the talks thinks there should be less plastic produced. Oil and gas compa…

Gen-T: Table Reclamation in Data Lakes
We introduce the problem of Table Reclamation. Given a Source Table and a large table repository, reclamation finds a set of tables that, when integrated, reproduce the source table as closely as possible. Unlike query discovery problems like Query-by-Example or by-Target, Table Reclamation focuses on reclaiming the data in the Source Table as fully as possible using real tables that may be incomplete or inconsistent. To do this, we define a new measure of table similarity, called error-aware i…
