Vatnajökull National Park: A Landscape of Fire and Ice
Vatnajökull National Park, officially known as "Vatnajökull National Park - Dynamic Nature of Fire and Ice," is a breathtaking natural wonder located in southeastern Iceland. Covering an expansive area of approximately 1,400,000 hectares, or around 14 percent of Iceland's total territory, it is the country's largest national park and one of its three national parks.
The park's name derives from the vast Vatnajökull glacier, which lies at its heart. This massive ice cap, the largest in Europe, stretches across a diverse landscape that includes ten central volcanoes, eight of which are subglacial. Two of these volcanoes, Grímsvötn and Bárdarbunga, are particularly active, contributing to the dynamic and ever-changing nature of the park.
One of the most striking phenomena associated with this volcanic activity is the jökulhlaup, a sudden flood caused by the breaching of a glacier margin during an eruption. These events have sculpted the park's unique topography, creating sandur plains, river systems, and rapidly evolving canyons. While occasional, jökulhlaups showcase the raw power of Iceland’s “fire and ice” landscape.
In addition to its geological features, Vatnajökull National Park is home to a diverse and unique ecosystem. The volcanic areas within the park provide habitat for endemic groundwater fauna that managed to survive the Ice Age. These unique organisms survive in the park's hot springs, geysers, and other volcanically heated water sources.
The park's northern section, previously known as Jökulsárgljúfur National Park, boasts impressive canyons, waterfalls, and basalt columns. Notable attractions here include Dettifoss, Europe's most powerful waterfall, based on volume of water flow, and Ásbyrgi, a horseshoe-shaped canyon believed to have been formed by ancient glacial floods.
In the southwestern corner, Skaftafell offers visitors a range of hiking trails through lush valleys, past cascading waterfalls, and up to the edge of the glacier itself. The park’s highest peak, Hvannadalshnúkur, rises to 2,110 meters above sea level, providing stunning views of the glaciers, volcanic landscapes, and surrounding wilderness.
Visitors to Vatnajökull National Park can witness firsthand the raw power and beauty of the stunning contrast between ice and volcanic activity. From the tranquil serenity of the glaciers to the explosive energy of the volcanoes, the park offers a unique glimpse into the forces that shaped our planet. As such, it is a must-visit destination for anyone seeking to experience the wonders of nature in all their glory.
UNESCO Description of the World Heritage Site
This iconic volcanic region covers an area of over 1,400,000 ha, nearly 14% of Iceland's territory. It numbers ten central volcanoes, eight of which are subglacial. Two of these are among the most active in Iceland. The interaction between volcanoes and the rifts that underlie the Vatnajökull ice cap takes many forms, the most spectacular of which is the jökulhlaup – a sudden flood caused by the breach of the margin of a glacier during an eruption. This recurrent phenomenon has led to the emergence of unique sandur plains, river systems and rapidly evolving canyons. Volcanic areas are home to endemic groundwater fauna that has survived the Ice Age.
UNESCO Justification of the World Heritage Site
Criterion (viii): The coexistence and ongoing interaction of an active oceanic rift on land, a mantle plume, the atmosphere and an ice cap, which has varied in size and extent over the past 2.8 million years, make the property unique in a global context. Earth system interactions are constantly building and reshaping the property, creating remarkably diverse landscapes and a wide variety of tectonic, volcanic and glaciovolcanic features. Especially interesting and unique in this regard are the basaltic lava shields (Iceland shields), volcanic fissures and cone rows, vast flood lavas, and features of ice dominant glacio-volcanism, such as tuyas and tindar. Interestingly, the well exposed volcanic features of the property have been used as analogues for similar features on the planet Mars. Geothermal heat and subglacial eruptions produce meltwater and jökulhlaups that maintain globally unique sandur plains, to the north and south of the Vatnajökull ice cap, as well as rapidly evolving canyons. In addition, the property contains a dynamic array of glacial- and geomorphological features, created by expanding or retreating glaciers responding to changes in climate. These features can be easily accessed and explored at the snouts of Vatnajökull’s many outlet glaciers and their forelands, especially in the southern lowlands, making the property a flagship glacial research location.

Structural and functional characterization of a hyperthermostable single‐stranded DNA ‐binding protein from a hot spring metagenome
Researchers have identified and characterized a hyperthermostable single-stranded DNA-binding protein (SSB-M5) from a hot spring metagenome in Vatnajökull National Park, Iceland. This small protein, derived from hyperthermophilic Fervidobacterium species, demonstrates remarkable stability and high affinity for single-stranded DNA, even at temperatures up to 100°C. Structural analysis revealed that SSB-M5 forms a tetrameric functional unit, while biochemical assays confirmed its ability to substitute for Escherichia coli SSB in mutant strains. Notably, SSB-M5 exhibits cooperative binding with an EC50 of 141 pM and a Hill coefficient of 2, indicating strong and specific interactions with DNA. Its inclusion in PCR reactions significantly enhances amplification by eliminating non-specific products, highlighting its potential applications in molecular biology and biotechnology.

Every Grain Tells a Story: Deciphering Planetary Processes Through Sediment Transport on Earth, Mars, and Beyond
Sediment transport on Mars and other planetary bodies encodes critical information about past and present environmental conditions, yet interpreting these processes remains challenging due to differences in atmospheric density, gravity, and grain properties compared to Earth. Recent research at Oxia Planum, the future landing site of the ExoMars Rosalind Franklin rover, combines morphometric analysis of aeolian features like transverse aeolian ridges (TARs) and periodic bedrock ridges (PBRs) with advanced atmospheric modeling—including Mars Global Circulation Models (MGCMs), mesoscale models, and large eddy simulations (LES). These studies reveal that Martian sedimentary archives hold snapshots of climatic regimes, erosion rates, and sediment flux, providing insights into the planet's dynamic history. Terrestrial analogues, such as the hyper-arid Puna Plateau in Argentina, Lake Askja in Iceland’s Vatnajökull National Park, and Scotland’s Scoraig delta, serve as crucial references to refine interpretations of Martian landscapes. The work underscores the need for a holistic approach that integrates atmospheric forcing, grain-scale interactions, and terrestrial insights to decode planetary sediment transport—offering a template for studying similar processes across the solar system.

Intersecting heritage and tourism trajectories: territorial dynamics of geoheritage in UNESCO-labeled landscapes
UNESCO-labeled landscapes often see the interplay between geoheritage recognition and tourism development shape territorial dynamics, with outcomes varying based on local actors, institutional frameworks, and contextual factors like volcanic eruptions or economic crises. This study reveals that heritage and resource trajectories can unfold in distinct sequences—tourism preceding heritage designation (e.g., Swiss Alps), heritage leading to tourism (e.g., Vatnajökull National Park), or independent/strongly interdependent dynamics (e.g., M'Goun or Katla UNESCO Global Geoparks). The research highlights that while UNESCO labels may not always guarantee optimal geoconservation, they influence how geoheritage is integrated—or excluded—from protected areas, posing future management challenges. By analyzing case studies across the Swiss Alps, Moroccan Atlas, and southern Iceland, the study underscores the need to systematically examine heritage awareness, value hierarchies, and institutional constraints to mitigate tourism pressures on sensitive geomorphological environments.

Proglacial lake development and outburst flood hazard at Fjallsjökull glacier, southeast Iceland
A significant expansion of Fjallsárlón proglacial lake, fed by Fjallsjökull glacier in Vatnajökull National Park, is projected if current retreat rates persist. By 2110, the lake could more than double in surface area and triple in volume, occupying two overdeepened basins with a maximum depth of ~210 m. This expansion may accelerate glacier melting and calving, potentially floating the glacier tongue. The study also identifies three high-risk zones on valley walls where rockfalls or avalanches could trigger displacement waves or glacial lake outburst floods (GLOFs), posing hazards to visitors and infrastructure. Using multibeam sonar surveys, researchers mapped lake development from 1945 to 2021, providing critical data for risk assessment and mitigation strategies at this UNESCO World Heritage Site.

A hydrogeological conceptual model of aquifers in catchments headed by temperate glaciers
Researchers have identified two distinct aquifers with varying hydraulic conductivities in the catchments of four south-eastern outlet glaciers of Vatnajökull, Iceland. They found that glacial meltwater recharge is significantly higher—four times greater—under the glaciers compared to adjacent plains, revealing a critical link between glacier dynamics and groundwater systems. This discovery provides a new hydrogeological conceptual model that enhances our understanding of water resource evolution under climate change, as well as potential risks from floods and landslides in glacial contexts.

Distribution of Woody Biomass on the Outwash Plain of a Retreating Glacier in Southern Iceland: Role of Microhabitat and Substrate
A study of Skaftafellsjökull, an outlet glacier in southern Iceland retreating since 1890, reveals that the outwash plain's microhabitat—specifically its channels and swales—hosts a higher concentration of woody biomass, dominated by Betula pubescens (downy birch), than the moraines. Despite occupying less area, these fine-grained substrates within channels foster successful seeding and growth, leading to greater mean woody biomass on the outwash plain compared to moraines. The research combines field observations with topographic analysis to highlight how substrate heterogeneity influences vegetation distribution in glacier forelands.
