An engineering firm was in the process of refurbishing a relatively small ferryboat terminal in the Northeast, when an intact, massive - and potentially explosive - Rodman cannonball was unearthed by a backhoe. In their latest case study, Aqua Survey describes how they surveyed the work zone for other unexploded ordnance to ensure worker safety. Aqua Survey News. April 4, 2. 01. 7 applied. Netherlands- based N- Sea has selected Geosoft’s Oasis montaj and UXO Marine software to detect unexploded ordinance that pose a hazard to its customers operating in the North Sea and other offshore regions. N- Sea surveys, inspects, maintains and repairs subsea infrastructure for the oil and gas and windfarm industries using a fleet of ships and teams of divers, ROV pilots and surveyors.

Johannesburg in South Africa. Read the full article»December 1, 2. A longstanding debate about whether granitic magmas in England ascended through the crust as diapirs or along networks of dykes to form tabular structures has taken a step closer to resolution. A 3. D model of the St Austell pluton, one of six major plutons associated with the Cornubian batholith of Southwest England, suggests the pluton is comprised of at least two separately intruded sheets of granite. Starting with the basics, this article summarizes methods that can be used for magnetics, gravity, elevation, electromagnetic grids and the list goes on. Linked. In Pulse. October 3, 2. 01. Gravity and magnetic methods are an essential part of oil exploration. Rather, they add to it. Despite being comparatively low- resolution, they have some very big advantages. At a comparatively low cost, airborne potential field surveys can provide coverage of large areas. The area of study is the Moldanubian Pluton, part of a tectonic zone formed in central Europe 3.

This article reviews proven exploration techniques that can be used to successfully explore for lithium around the globe. Mining Geology HQAugust 1. Expertise. Erik Ronald, Director of Mining Geology HQ, shares some fundamental aspects to ensure success when conducting geological mapping. The area covers more than 2. Read the full article»August 4, 2. Expertise. Geoscience data is to exploration what road systems are to transport: a precompetitive asset that jurisdictions must provide if they hope to foster a viable and sustainable mining industry. Jurisdictions willing to provide the data necessary to begin the search for buried deposits will reap the benefits of the next generation of mines predicts Jon Hronsky, principal of Western Mining Services.

National Corvette Museum in Bowling Green, Kentucky, USA, captured stunning footage of a sinkhole opening up and swallowing eight classic Corvette cars. Within hours of the disaster, a team of museum staff, general contractors, geotechnical and civil engineers, karst scientists, and Corvette enthusiasts had assembled onsite to survey the damage and guide the recovery.

Researchers at Monash University are using grid analysis techniques to determine the structural controls on the Newer Volcanics Province in south- eastern Australia. The analysis included grids for both Bouguer gravity and reduced to pole magnetic anomalies. Read the full article»February 2. Ocean scientists work in not just three but four dimensions, including time, so presenting data in a way that others can understand can be challenging. One solution is to reduce the 4. D data cube to three dimensions by taking a slice of time or another dimension, such as depth. Read the full article»February 8, 2. Deloitte published its global mining report, Tracking the Trends 2. China. Read the full article»February 4, 2. Falling oil prices have put enormous financial pressure on all producers, especially the high- cost producers in the new shale resource plays. These “unconventional” producers will be the first to cease operations, thus reducing the supply and increasing the price, explains Leon Thomsen, Chief Scientist with Delta Geophysics, unless they find a better way to conduct their operations.
