Measuring Underwater Noise: Protecting Marine Life and Powering Ireland
Introduction: A quiet revolution beneath the waves As Ireland advances its offshore wind ambitions, researchers are turning a critical eye to an often overlooked factor: underwater noise. The hum and crash of marine traffic, pile-driving during turbine installation, and ongoing operational sounds from turbines all contribute to a complex acoustic environment. Measuring underwater noise is…

Ancient Parasites Rewrote History: 480-Million-Year-Old Fossil Reveals Early Parasitism
Groundbreaking fossil reshapes our view of parasitism A remarkable fossil finding from Morocco is rewriting a chapter in the story of life on Earth. Researchers have identified parasitic worms burrowing into mollusc shells in the Fezouata Shale, dating to roughly 480 million years ago. This discovery pushes back the known onset of parasitism by about…

Ocean Warming Threatens Prochlorococcus, Key Oxygen Producer
The Vital Role of Prochlorococcus in Earth’s Ecosystem Earth’s biosphere heavily relies on photosynthesis, primarily conducted by organisms like plants, algae, and especially Prochlorococcus. This marine cyanobacterium is recognized as the most abundant photosynthetic organism on our planet, contributing nearly a third of the oxygen produced globally. Its tiny size belies its enormous ecological impact,…

Impact of Ocean Acidification on Shark Teeth and Ecosystems
Understanding Ocean Acidification Ocean acidification is a pressing environmental issue resulting from increased levels of carbon dioxide (CO2) in the atmosphere. As we burn fossil fuels and conduct other industrial activities, excess CO2 is absorbed by the oceans. This process leads to a decrease in pH levels, causing the water to become more acidic. Recent…
