Pacific Ocean Floor - Yellow Brick Road

Introduction to the Discovery

The Ocean Exploration Trust’s research vessel E/V Nautilus made a remarkable discovery on the Pacific Ocean floor during an expedition. A strange formation, resembling a yellow brick road, was found at a depth of 1,029 metres near Nootka Seamount, within the Papahānaumokuākea Marine National Monument.

The structure’s unusually regular pattern made it resemble a brick sidewalk, but scientists identified it as a natural geological formation. According to a report published by The Oceanography Society on the Ocean Exploration Trust’s 2022 field season, the formation likely consists of fractured hyaloclastite, a type of volcanic rock created when hot magma meets cold water.

The Formation’s Characteristics

Researchers suggested that the yellow colour of the formation likely resulted from low-temperature hydrothermal alteration of the volcanic glass. The formation’s fractures intersect at right angles, giving it the look of a brick sidewalk. The resemblance prompted the description ‘yellow brick road’, but the appearance did not indicate that people had built or laid anything there.

The report explains that the formation likely consists of hyaloclastite, which forms when hot magma comes into contact with cold water, causing volcanic material to break into fragments. Scientists said the surface likely represents fractured hyaloclastite, rather than a constructed pathway.

Volcanic Activity on the Seafloor

The report attributes the formation to volcanic activity on the seafloor. The geometry of the formation may look carefully arranged, but it is part of the rock’s natural structure. The yellow appearance also has a natural explanation, with the colour likely developing through low-temperature hydrothermal alteration of the volcanic glass.

Hydrothermal alteration refers to changes caused when heated fluids interact with rock. In this case, the report presents it as the likely reason for the colour. Together, the fractured rock, right-angled cracks and altered volcanic glass give the seafloor feature the appearance of a road, although it was formed through natural geological activity in the area.

Other Discoveries from the 2022 Field Season

The yellow brick road was one finding from the 2022 field season aboard E/V Nautilus. The report describes a wider programme of seafloor mapping, remotely operated vehicle dives and work with autonomous systems. It records 120 uncrewed vehicle deployments during the season.

The expeditions also documented deep-sea coral and sponge communities, fossilised whale bones and a fossilised Megalodon tooth. Researchers observed and collected a sea pen from the genus Solumbellula, marking its first recorded observation and collection in the Pacific, according to the report.
