The AIPG National Office is closely monitoring the COVID-19 outbreak. At this time, AIPG staff have canceled travel until May 1. In addition, the AIPG National Office Staff have gone to a 85% telework schedule. The AIPG Staff WILL BE AVAILABLE to take your calls, answer your questions, and provide the excellent services that our members have come to expect. We are taking every action to insure that member data will not be compromised as we work from home. If you have any questions, comments or concerns, please feel free to reach out to us at aipg@aipg.org.

This webinar covered what it takes to succeed while working for yourself. Topics include why consultants get hired, the pros and cons of consulting, and whether or not you might be a good fit. The webinar delved into the risks of consulting and how to minimize them ... financing and promoting your business, the most critical element in making a "go" of it, how much to charge for your work, executing a job and how to get paid.

Crystalline rocks are generally characterized by negligible porosity and permeability in terms of groundwater exploitability. However, alteration processes can greatly increase their fracture permeability and induce formation of modest, but locally important aquifers. Therefore, subsurface characteristics of alteration zones are of major importance for hydrogeological evaluation of crystalline terrains.

Earth's molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet.
The boundary between the liquid iron core and the rocky mantle is located some 1,800 miles (2,900 km) below Earth's surface. At this transition, the temperature drops by more than a thousand degrees from the hotter core to the cooler mantle. The new study, published in the journal Nature Geoscience suggests heavier iron isotopes migrate toward lower temperatures — and into the mantle — while lighter iron isotopes circulate back down into the core.

Journal of Hydrology: Regional Studies
The focus of this study is the development and subsequent application of a computationally-efficient framework for parsimonious hydrological models to simulate impact of land cover changes. The framework was applied to the NAM conceptual model, considering the disaggregation approach by Tran et al. (2018), and urban development scenarios for the study region for 2050.

Nature Scientific Reports
Organic matter production and decomposition primarily modulate the atmospheric O2 and CO2 levels. The long term marine primary productivity is controlled by the terrestrial input of phosphorus (P), while the marine P cycle would also affect organic matter production. In the past 540 million years, the evolution of terrestrial system, e.g. colonization of continents by vascular land plants in late Paleozoic, would certainly affect terrestrial P input into the ocean, which in turn might have impacted the marine primary productivity and organic carbon burial. However, it remains unclear how the marine P cycle would respond to the change of terrestrial system.

The time of origin of the geodynamo has important implications for the thermal evolution of the planetary interior and the habitability of early Earth. It has been proposed that detrital zircon grains from Jack Hills, Western Australia, provide evidence for an active geodynamo as early as 4.2 billion years (Ga) ago. However, our combined paleomagnetic, geochemical, and mineralogical studies on Jack Hills zircons indicate that most have poor magnetic recording properties and secondary magnetization carriers that postdate the formation of the zircons.
