| Throughout | Reference to Ugrib as a GRIB viewer and source of GFS data. | Ugrib discontinued business a couple years after the 2nd ed. of the text was published. There are many new and much improved options now available. |

Figure 7.2-5 Caption. It should be clear from the picture, but it will be more consistent and clearer to change this 4th line insert: (NE 12 kts on the left with a true wind angle of 160, 20 kts on the right with a true wind angle of 170).

to read: (NE 12 kts on the left with a true wind angle of 160; E 20 kts on the right with a true wind angle of 170). We had left out the E descriptor on the right side discussion, and changed , to ;.

| p. 70 | states that "...on average we might see quadrant changes (W to SW or SW to W, etc.) every week or two..." | This phrase is too specific. It should be broader as there is much
variation in this. Perhaps these changes could be expected "every
few days to every few weeks." The statement was based on an idealized pattern, which simply does not occur often enough to justify the time frame originally stated. Best bet is look at a few of the actual animations of these winds at OPC over some period of time to see how this varies. Here is a note from our online course: Here are some sample youtube videos of winds aloft. They are just examples, and not particularly good examples to illustrate our discussion other than showing the variation we can expect. We also make a youtube of the do it yourself pdf animation we use in class, but probably one can see more from the pdf where it is manually controlled. Here is where to get loops at any time for any ocean or level. http://www.opc.ncep.noaa.gov/Loops/ atlantic winds aloft http://youtu.be/TYrjolzw41M pacific winds aloft http://youtu.be/PzRMlhfxXKo How weather maps evolve http://youtu.be/P2rWhd0PEQk |
| p. 102. | Table 4.2-1 Tropical storm winds 33 to 63 kts | This should be 34 to 63 kts. |

Fig 7.1-1 caption. " Lightship November" not quite right. | Not curcial to the content of the book, but the N marked the location of Ocean Station November, ie N was name of the station and not the vessel. The N appeared on charts up to the 1980 edition, maybe a bit longer. see http://www.uscg.mil/history/webcutters/rpdinsmore_oceanstations.asp The vessel stationed there did indeed have bright navigation light, but also had a radio beacon 335 sending morse letters YN at HH + 05, 20, 35, 50m

| p. 316 | Fig. 10-6.1 caption refers to the coast of "Columbia." | This is a typo. The country name is Colombia.

| Throughout, but mainly Chapters 2 and 7 | We refer to programs that assist with weather analysis, either to view grib files or to georeference actual weather maps in a navigation program. Some of those we referred to have changed or transitioned from free programs to commercial programs. | We can recommend options for these functions, including those from opencpn.org and from expeditionmarine.com. Both offer GRIB overlays, importing and georeferencing weather maps, and optimizing sailing routes using GRIB data and polar diagrams. Coastal Explorer from Rose Point also displays GRIB data, and Nobeltec TZ shows GRIB data along with a convenient optimal weather routing tool. OpenCPN is a free program; the others are commercial products with trial periods available. |
| Throughout | All discussion of scatterometer data | Since the publication of this edition, the new RapidScatt scatteromer data are now available. This instument is on the International Space Station and provides a nice broad swath of data, similar to what we had with QuikSCAT. See OSWT page in the Data Products section. The use and value of such data does not change; there is just a nice new source of data. On the other hand, we have lost the OSCAT data from India that we do discuss in the book. This was rather short lived, which illustrates the challenges of this technology.
