tomSea & EMBIIOutput 2 is a change, so it contains no data and has been excluded. Change appear to be randomly placed in the list of output of the uploads, but they can be easily removed because they are the only output with a different value.
The newlines shown above are explicitly encoded as CR LF newlines with characters 0d 0a.
396 is the number of payload bytes between 396*8881a937a437ff6ce83be3a89d77ea88ee12315f37f7ef0dd3742c30eef92dba and the last txid 39348722b841afa0c5b67e5af10839afe965ed1b24874e89336bea9fa4ef3091, including newlines but exclusding the last line.Now let's inspect the transactions linked to from toplevel.
tx 8881a937a437ff6ce83be3a89d77ea88ee12315f37f7ef0dd3742c30eef92dba contains only payloads without any change. It starts with the following UTF-8 string with CR LF spaces;
