7 -Broadband (or BB) sensors are especially sensitive to low frequency energy, and are //broad//ly defined as any instrument capable of **reliably recording wave periods greater or equal to 10 seconds**. This makes them useful for analysis and detection of teleseismic earthquakes as well as techniques involving ambient noise. However they are also well-suited for measuring high frequency energy, limited only by the Nyquist frequency of the [[data logger>>doc:Instrumentation.ANU LPR-200.WebHome]]'s sampling rate. The downside to broadband sensors is usually their cost, size, and fragility relative to short period sensors.
7 +We usually pack equipment on pallets, in transporter cases, or in boxes. This depends on a range of factors, including:
8 8  
9 -== Nanometrics ==

10 +* shipping method (air, sea, road/rail)
11 +* access for inspectors en route (e.g., customs or dangerous goods).

13 +In most instances, we provide dimensions for the borrower to quote and book freight directly with their preferred carrier. This simplifies billing and insurance arrangements. However, we will still assist with technical details throughout your booking if needed.

23 +At minimum, we ask users to follow the basic checklists below for sites in __low-risk__ biosecurity areas. If you are working in higher-risk areas, please discuss your field hygiene plan with us as early as possible, so we can coordinate pre and post-treatments.
22 22  
23 -Short period (SP) sensors have limited sensitivity to longer periods, but are otherwise perfectly suitable for earthquake or other high frequency analysis. They are generally defined as any instrument that begins to **lose sensitivity at periods larger that 10 seconds**. They tend to be smaller and more mechanically robust to broadband sensors.
