Jan 24, 2019 at 12:41 comment added Pieter Geerkens The Access Database Engine has always been a free, redistributable, download. What you pay for is the design tools associated with it. Any database-aware application, such as Excel or MS-SQL, can read MDB and ACCDB files once the appropriate vintage of the JET Engine has been installed. There are 32/64-bit issues to be aware of however.

Added working link to ship log data
Jan 24, 2019 at 11:22 comment added kimchi lover Are CLIWOC entries representative of merchant shipping voyages? Pieter Geerkens's answer shows only warships visiting Halifax, for instance, and the input data to the CLIWOC project seems to have a built-in selection bias.

Jan 24, 2019 at 9:55 comment added sempaiscuba @PieterGeerkens the link at projects.knmi.nl/cliwoc/download/cliwoc15.htm seems to work.
Jan 24, 2019 at 0:33 comment added Pieter Geerkens @SteveBird: I take "Not so; a major change was made in the file formats when they switched from .mdb to .accdb" as a challenge - however the link appears to be broken for the file CLIWOC15_2000.zip. I'm willing to make a modest effort at retrieval if someone can supply me with the zip file. I so have an Access 2010 DVD; and other programming tools in my kit should be able to read the database files also.
Jan 23, 2019 at 23:07 comment added Peter Diehr @SteveBird: Not so; a major change was made in the file formats when they switched from .mdb to .accdb. Microsoft says "To work around this issue, use a pre-Access 2013 version of Access to save the Access 97 database as an .accdb file: ". Unfortunately, I don't keep older versions, nor are they available from MS.
Jan 23, 2019 at 22:25 comment added Steve Bird Modern versions of MS Access should still be able to open a Access .mdb format database.

Explained the map.
Jan 23, 2019 at 21:28 comment added KillingTime The source of the map is James Cheshire at Spatial Analysis, who took the log data from the CLIWOC project database. The database itself is no longer accessible on that site but you might be able to track it down somewhere on the internet. That data should give you a good indication of what you want to know.

Clarification
Jan 23, 2019 at 16:13 comment added Pieter Geerkens It's not clear to me what you are referring to as "this shipping trade". Are you looking for ports with regular export / import to Halifax, NS? That seems the only possible meaning, but your choice of wording makes even that unclear.
