Also consider the length & diameter. Lengths of 20" are available for longer cores. Straws can also be inserted into one another for longer cores. This works best with two straws of slightly different diameters. Remember, the most common tree core diameter is 5.15mm, so diameters of 7-8mm work well.

FHAES analyzes event chronologies such as those from fire-scarred trees but can also be used to analyze chronologies of other disturbance events, like avalanches, floods, freezes, or insect infestations.

Dendroarchaeology calls for special borers made for taking (usually) larger core samples from dry timbers and artifacts. These bits are used in combination with an electric drill.

Sercon are dedicated to the design, manufacture and support of Isotope Ratio Mass Spectrometers and their associated sample preparation systems.

Many dendroarchaeologists use coring bits designed specifically for them by local makers. It's never a bad idea to ask a dendroarchaeologist which borers they prefer to use.

​MAIDEN is an ecophysiological model that was created to explore the relationships between climate variability and forest growth-productivity. The simulations are verified using dendroecological data and measurements of ecosystem fluxes.

Provides novel dendroclimatological methods, primarily used by the Tree-ring research community. There are four core functions. The first one is daily_response(), which finds the optimal sequence of days that are related to one or more tree-ring proxy records. Similar function is daily_response_seascorr(), which implements partial correlations in the analysis of daily response functions. For the enthusiast of monthly data, there is monthly_response() function. The last core function is compare_methods(), which effectively compares several linear and nonlinear regression algorithms on the task of climate reconstruction. - Dr. Jernej Jevsenak (GitHub)

WinCELL is an image analysis software program specifically designed for wood cells analysis. It can quantify the changes in wood structure over annual rings.

sgsR is designed to implement structurally guided sampling approaches for enhanced forest inventories. The package was designed to function using rasterized airborne laser scanning (ALS; Lidar) metrics to allow for stratification of forested areas based on structure.

Hugin provides the ability to stitch photos together. For dendrochronologists, this means we can take multiple scans of large cores or cross sections and stitch them together for image analysis in other crossdating software.

DENDROXRAY 2 closed system is a compact designed apparatus for the gentle X-raying of wood samples. The X-ray tube of the DENDROXRAY 2 closed system is built-in into a cabinet, which protects the operator against all X-rays coming out from the X-ray tube (fully protected device). This equipment has the advantage (in Switzerland) that no approval is necessary for the operation.

Core mounts are essential to dendrochronologists. There's no exact rule on how they have to be made as long as the essentials are present: Straight wood strips with a groove down the middle is the very basic form, and the function is to glue wood cores to it for better sanding/cutting/viewing/storage of tree-rings.

dplR is a software package in the R statistical programming environment for tree-ring analyses. R is the world's preeminent open-source statistical computing environment where users can contribute packages, which are freely available on the internet. dplR can read standard format files and perform several standard analyses. These include interactive detrending, chronology building, and calculating standard descriptive statistics. The package can also produce a variety of publication quality plots. - Dr. Andy Bunn (GitHub)

Smartborer is a device for automatic sampling of increment cores by converting high-speed, low-torque input from a battery-operated Makita electric wrench to a low-speed, high-torque output. Three models available for sampling: 1) 5-mm cores of soft- and hardwood, 2) 12-mm cores of softwood, and 3) 12-mm cores of hardwood. It is capable of sampling an increment core in three minutes, as shown in these videos.

Like many tools, chainsaws come in a variety of brands & sizes depending on your needs and budget. Some important criteria to consider are weight, engine size & bar length to match size of trees/remnant wood you sample, price, and brand reputation.

Buying a chainsaw is good, but you're going to need some things to go with it. Below are some necessities and considerations to assure a good time is had in the field.

The new Skippy system allows digitizing tree rings from cores and disks, but also taking images from long micro sections (up to 40cm) using transmitted light. This feature is of special interest for dendrogeomorphic applications to identify the onset of compression wood and tension wood in micro sections cut with a WSL-Core-Microtome.

Titan USA earned its stellar reputation by providing machinists like yourself with premium quality, American-made cutting tools. When you're in need of everything from end mills and drills to taps and reamers, Trust in Titan USA to deliver the best quality tooling at incredible value.

An important factor in deciding what kind of straws to use in the field is the amount of moisture you'll be working in. Paper straws are more breathable and better at preventing mold, but if you are working in wet/humid environments, it might be best to go with plastic.

We build scanners by scientists for scientific work in research and industry, scanners that maximize your analytical possibilities and the information that you can pick up from your samples. Still, these scanners are straightforward and easy to use. With these instruments you can scan along long samples to determine the variation of a wide range of elements along a scanned track. Our Itrax XRF scanners retrieve a wealth of information in short time, non destructively and cost efficient. A deep understanding of x-ray physics have resulted in several cutting edge constructions. Itrax stands for XRF scanners with unique constructions packed with innovations that offer several competitive advantages. These analytical instruments find their applications in scanning drill cores as well as wet sediment cores or even wood, within fields like Geology, Petroleum Engineering and Research, Mineral Exploration and Research, Forestry, Environmental Research, Paleoclimate Research, etc.
