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 the 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 ==
9 +* staff and facilities available at your institute
10 +* shipping method (air, sea, road/rail)
11 +* access for inspectors en route (e.g., customs or dangerous goods).
10 10  
11 -Currently, 4 kinds of nanometric broadband seismic sensors are available. The Trillium Compact 120, Trillium Compact 20, Trillium Compact Posthole, and most recently, the Trillium Compact Horizon. These seismometers are ideal for long-term deployments of multiple months. All of these seismometers are compatible with the LPR-200 and TSAWR loggers and are designed for low energy consumption.
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.

13 -=== Trillium Compact 120 ===
15 +Directions for return freight will be provided with your Supply Agreement.
14 14  
15 -The Trillium Compact 120 has sensitivity band between 120 seconds and 100Hz but is prone to corrosion when buried for long periods. They have a tilt tolerance of ~~10° but come with adjustable feet for leveling.

19 -=== Trillium Compact 20 ===
21 +Plan ahead to ensure your teams have the time and tools they need to avoid moving organic material between sites and regions. Factors to consider include site conditions, vehicle capacity, water and laundry access.
20 20  
21 -The Trillium compact has a recording range between 20 seconds and 100H. but is prone to corrosion when buried for long periods. They have a tilt tolerance of ~~10° but come with adjustable feet for leveling.
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 -For more information, refer to the Nanometrics instrument information sheet: [[https:~~/~~/nanometrics.ca/hubfs/Downloads/Data%20Sheets/trillium_compact.pdf?hsLang=en-ca>>https://nanometrics.ca/hubfs/Downloads/Data%20Sheets/trillium_compact.pdf?hsLang=en-ca]]
25 +**Before install: **We will do our best to supply clean instruments, but please do a quick final check for seeds and stowaways before burial.

27 +**Before leaving the site:**
26 26  
27 -The Trillium Compact Posthole is designed with a robust casing allowing it to be deployed via direct-burial without a vault or protective case. It does NOT have leveling feet nor a bubble (**bring your own!**), nor can its mass be rebalanced remotely. The cable is also quite a bit more stiff so may require burial at an increased depth. If installed inside a vault, the cable may also unbalance the sensor if left by itself. The instrument response is identical to a Trillium Compact 120.
29 +1. Brush off as much dirt as possible.
30 +1. Inspect crevices for insects, eggs, seeds, etc.
31 +1. Wipe instruments clean if placing directly into foam or textile cases.

33 +**Before packing equipment for return:**
30 30  
31 -=== Trillium Compact Horizon ===
35 +1. Check again for insects and loose debris.
36 +1. Check that data cards are removed (and safely stored).
37 +1. Wipe surfaces clean with diluted castile or other mild soap (keeping connectors and electronics dry).
38 +1. Let everything dry well before packing.
32 32  
33 -The Trillium Compact Horizon is sort of a mix between the Posthole and Compact 120, ideal for shallow direct bury deployments or instances where packing weight and size is an important consideration. Its response and sensitivity is identical to the Trillium Compact 120
40 +Note: Our technicians will clean connectors and tougher stains in the lab.
34 34  
35 -**~*~*ADD PICTURES~*~***
42 +If your field hygiene plan requires treatments stronger than regular soap or warm water, please discuss with us first.
36 36  
37 -=== SmartSolo Broadbands ===
44 +**Can we pay ANU Earth Imaging to do it for us?**
38 38  
39 -Two types of SmartSolo brand seismometers are currently available, one of which is a broadband seismometer. More information is available on the SmartSolo Seismometers page.
46 +No, sorry. We recommend 'cleaning as you go' to minimise movement of organic material, and this includes movement back to our territory and campus. We understand this wasn't always considered necessary, and appreciate how quickly and willingly the community has adapted to this change.
40 40  
41 -= Short period sensors =
48 +Your efforts also directly improve our research and support capacity, as dirty returns complicate operations in our lab and workshop.
42 42  
43 -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 than 10 seconds**. They tend to be smaller and more mechanically robust to broadband sensors.
50 +**How clean is clean enough?**

54 +There will often be a few missed spots, which is why we do a second check before testing, and a third check before packing for the next experiment.
