Volcanoes have many stories to tell, and their activity profoundly impacts, and their activity profoundly impacts and their activity profoundly impacts human life and Earth’s environment. In this issue ofand Earth’s environment. In this issue ofEarth’s environment. In this issue of Scientific Drilling, a report on the Hawaii Drilling Project highlights “hot spot” volcanism (p. 4). A decade of planning and drilling on the island of Hawaii resulted in 3500 m of drillcores from lava flows piled up by the Mauna Loa and Mauna Keadrillcores from lava flows piled up by the Mauna Loa and Mauna Kea volcanic systems. Detailed analyses tell an intriguing story about the Earth’s mantle down to 3000 km depth, and how the volcanoes, rising 10 km from the seabed, formed over time and host an unexpected hydrogeological system. Planned drilling in Kamchatka (p. 54) will address the source of energy and water driving hydrothermal systems in volcanoes typical of the Pacific Ring of Fire. And, a report on the potential for ocean drilling to, a report on the potential for ocean drilling to a report on the potential for ocean drilling to address volcanic, seismogenic, and other geohazards is presented on p. 15.

Climate and environmental change are at the top of global research initiatives. The environment in which life flourished 3.2 billion years ago is the target for drilling in northwestern Australia (p. 34). Drilling into a lake in southeastern Europe holds the potential to recover much more recent records of environmental evolution linked to an amazing biological speciation (p. 51). The quest for drilling cores at high latitudes significantly The quest for drilling cores at high latitudes significantlyThe quest for drilling cores at high latitudes significantlys significantly significantly depends on the ability to image targets seismically (p. 40) and the ability to cope with challenging logistics (p. 38).

Taken together, the fundamental contributions by scientific drillings by scientific drilling by scientific drilling projects to understanding Earth’s environment and its immense naturaling Earth’s environment and its immense natural Earth’s environment and its immense natural variability over geological time should leave no doubt about their impor-tance. Unfortunately, delays in drilling platform refurbishment and repair, and unavailability of mission-specific platforms—all related to an overheated-specific platforms—all related to an overheatedspecific platforms—all related to an overheated offshore and shipyard market—have caused an almost three-year-long-year-longyear-long-longlong drilling hiatus during IODP’s initial five years.
